Initial work on a tables lib

Incomplete lib intended to offer tables for all cryptographic libraries expecting them. Right now, it creates the tables at runtime. While that would still offer improvements, ideally large tables are built at compile time and simply entered into memory at runtime. My best idea for that was a linked list in the binary itself, where this app (at first call), reads a table stored to a section of data, then grabs the next reference to one and continues reading. The main issue with this idea, besides not yet researching how to encode data into the binary, was the fact the same table would be saved to disk multiple times under this simplistic model. An O(n) iteration when writing to the bin could potentially solve that. Related https://github.com/serai-dex/serai/issues/41.

-# Contributing
-
-Contributions come in a variety of forms. Developing Serai, helping document it,
-using its libraries in another project, using and testing it, and simply sharing
-it are all valuable ways of contributing.
-
-This document will specifically focus on contributions to this repository in the
-form of code and documentation.
-
-### Rules
-
- Stable native Rust, nightly wasm and tools.
- `cargo fmt` must be used.
- `cargo clippy` must pass, except for the ignored rules (`type_complexity` and
-`dead_code`).
- The CI must pass.
-
- Only use uppercase variable names when relevant to cryptography.
-
- Use a two-space ident when possible.
- Put a space after comment markers.
- Don't use multiple newlines between sections of code.
- Have a newline before EOF.
-
-### Guidelines
-
- Sort inputs as core, std, third party, and then Serai.
- Comment code reasonably.
- Include tests for new features.
- Sign commits.
-
-### Submission
-
-All submissions should be through GitHub. Contributions to a crate will be
-licensed according to the crate's existing license, with the crate's copyright
-holders (distinct from authors) having the right to re-license the crate via a
-unanimous decision.

+experience. Funds are stored in an economically secured threshold multisig
 wallet.

-[Getting Started](spec/Getting%20Started.md)

 ### Layout

- `audits`: Audits for various parts of Serai.
+- `docs` - Documentation on the Serai protocol.

- `spec`: The specification of the Serai protocol, both internally and as
-  networked.
-
- `docs`: User-facing documentation on the Serai protocol.
-
- `common`: Crates containing utilities common to a variety of areas under
-  Serai, none neatly fitting under another category.
-
- `crypto`: A series of composable cryptographic libraries built around the
-  `ff`/`group` APIs, achieving a variety of tasks. These range from generic
-  infrastructure, to our IETF-compliant FROST implementation, to a DLEq proof as
-  needed for Bitcoin-Monero atomic swaps.

+- `coins` - Various coin libraries intended for usage in Serai yet also by the
  wider community. This means they will always support the functionality Serai
  needs, yet won't disadvantage other use cases when possible.

+- `processor` - A generic chain processor to process data for Serai and process
  events from Serai, executing transactions as expected and needed.
-
- `coordinator`: A service to manage processors and communicate over a P2P
-  network with other validators.
-
- `substrate`: Substrate crates used to instantiate the Serai network.
-
- `orchestration`: Dockerfiles and scripts to deploy a Serai node/test
-  environment.
-
- `tests`: Tests for various crates. Generally, `crate/src/tests` is used, or
-  `crate/tests`, yet any tests requiring crates' binaries are placed here.

-### Security
-
-Serai hosts a bug bounty program via
-[Immunefi](https://immunefi.com/bounty/serai/). For in-scope critical
-vulnerabilities, we will reward whitehats with up to $30,000.
-
-Anything not in-scope should still be submitted through Immunefi, with rewards

@@ -4,46 +4,4 @@ A modern Monero transaction library intended for usage in wallets. It prides
 itself on accuracy, correctness, and removing common pit falls developers may
 face.

-monero-serai also offers the following features:
-
- Featured Addresses
- A FROST-based multisig orders of magnitude more performant than Monero's
-
-### Purpose and support
-
-monero-serai was written for Serai, a decentralized exchange aiming to support
-Monero. Despite this, monero-serai is intended to be a widely usable library,
-accurate to Monero. monero-serai guarantees the functionality needed for Serai,
-yet will not deprive functionality from other users.
-
-Various legacy transaction formats are not currently implemented, yet we are
-willing to add support for them. There aren't active development efforts around
-them however.
-
-### Caveats
-
-This library DOES attempt to do the following:
-
- Create on-chain transactions identical to how wallet2 would (unless told not
-  to)
- Not be detectable as monero-serai when scanning outputs
- Not reveal spent outputs to the connected RPC node
-
-This library DOES NOT attempt to do the following:
-
- Have identical RPC behavior when creating transactions
- Be a wallet
-
-This means that monero-serai shouldn't be fingerprintable on-chain. It also
-shouldn't be fingerprintable if a targeted attack occurs to detect if the
-receiving wallet is monero-serai or wallet2. It also should be generally safe
-for usage with remote nodes.
-
-It won't hide from remote nodes it's monero-serai however, potentially
-allowing a remote node to profile you. The implications of this are left to the
-user to consider.
-
-It also won't act as a wallet, just as a transaction library. wallet2 has
-several *non-transaction-level* policies, such as always attempting to use two
-inputs to create transactions. These are considered out of scope to
-monero-serai.
+Threshold multisignature support is available via the `multisig` feature.

-# Monero Generators
-
-Generators used by Monero in both its Pedersen commitments and Bulletproofs(+).
-An implementation of Monero's `ge_fromfe_frombytes_vartime`, simply called
-`hash_to_point` here, is included, as needed to generate generators.
-
-This library is usable under no-std when the `std` feature is disabled.
