* feat: add eip2930 tx type
* feat: add typed transaction enum
* chore: rlp_opt take reference to option
* feat: add eip-1559 tx type
* feat: add eip-1559 to the typed tx enum
* fix: references to rlp_opt / add access list setter
* chore: ignore etherchain and ethgasstation
Their APIs had a breaking change
* fix(1559/2930): serialize properly
1. The AccessList struct should have used RlpEncodableWrapper, otherwise we get extra bytes
2. The 1559/2930 types do not use eip-155-style replay protection
* feat: add helpers for operating on the txs enum
* chore: cargo fmt / lints
* feat(providers): return a PendingTransaction from send_tx calls
* feat(providers): expose the internal provider to all middlewares
* fix(middleware): use the returned PendingTx instead of using a hash
* fix(contract): use the pending tx returned value
Note1: To support that, we need to clone the tx when sending in order to make lifetimes work out
Note2: Multicall does not support that feature
* fix(ethers): adjust examples
* chore: fix provider test
* chore: fix celo test
