set up CI (#45)

* begin to setup ci

* attempt to fix build

* fix paths in build script

* fix

* satisfy clippy

* update fmt check to use nightly

* use nightly for build

* fmt

* fix fmt install

* update test script

* try to fix fmt

* merge w develop

* maybe fix build script

* install wasm toolchain

* install solc-select, use stable rust to build

* Correct clippy warnings

Currently intended to be done with:
cargo clippy --features "recommended merlin batch serialize experimental 
ed25519 ristretto p256 secp256k1 multisig" -- -A clippy::type_complexity 
-A dead_code

* Remove try-runtime

I tried to get this to work for an hour. I have no idea why it doesn't, 
yet it doesn't.

* Rewrite workflow

Splits tasks into a more modular structure. Also uses 
actions-rs/toolchain.

* Add a cache

* Immediately try building ETH/Monero while this is fixed

Adds solc-select use.

* Revert selective advance building of ETH/XMR

ETH builds now, so it hopefully should work now.

Also moves from on push to on push to develop.

* Install Monero runtime dependencies

Specify missing Rust toolchain setting.

* Correct multi-line commands

* Fix multi-line commands again

Cache Ethereum artifacts.

* Add Foundry

* Move Clippy under build

* Minimal rustup

Adds wasm Clippy. Puts Clippy before build.

* Use nightly clippy

* Remove old clippy call from under build

* Have the Monero build script support ARCH specification

Requirement for CI.

* Add WASM toolchain to tests

* Remove Ethereum cache which did not work as needed

* Remove extraneous quotes which broke builds on Arch
