Feature Request: Add support for more chains

[rappie]

I'd especially be interested in:

• Arbitrum
• Optimism

Optionally:

• Avalanche
• Gnosis

Sounds good! I'll put it on the backlog. If you are interested, you can also implement this yourself by adding these chains's info in

https://github.com/fuzzland/ityfuzz/blob/master/proxy/main.py#L49-L177 https://github.com/fuzzland/ityfuzz/blob/master/src/evm/uniswap/mod.rs#L390-L415 https://github.com/fuzzland/ityfuzz/blob/master/src/evm/onchain/endpoints.rs#L19-L119

A few new chains are supported in #130, but without flashloan support, which we are still working on
