Rename the coins folder to networks (#583)

* Rename the coins folder to networks

Ethereum isn't a coin. It's a network.

Resolves #357.

* More renames of coins -> networks in orchestration

* Correct paths in tests/

* cargo fmt

+# Monero Wallet
+
+Wallet functionality for the Monero protocol, built around monero-serai. This
+library prides itself on resolving common pit falls developers may face.
+
+monero-wallet also offers a FROST-inspired multisignature protocol orders of
+magnitude more performant than Monero's own.
+
+This library is usable under no-std when the `std` feature (on by default) is
+disabled.
+
+### Features
+
+- Scanning Monero transactions
+- Sending Monero transactions
+- Sending Monero transactions with a FROST-inspired threshold multisignature
+  protocol, orders of magnitude more performant than Monero's own
+
+### 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 wallet functionality 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.
+
+Finally, this library only supports producing transactions with CLSAG
+signatures. That means this library cannot spend non-RingCT outputs.
+
+### Cargo Features
+
+- `std` (on by default): Enables `std` (and with it, more efficient internal
+  implementations).
+- `compile-time-generators` (on by default): Derives the generators at
+  compile-time so they don't need to be derived at runtime. This is recommended
+  if program size doesn't need to be kept minimal.
+- `multisig`: Adds support for creation of transactions using a threshold
+  multisignature wallet.
