1559 Txs

[vezenovm]

Description

I added in the logic for checking whether the chain has forked to London and sending with the appropriate gas price. LockAndUpdateOpts tests whether the header of the most recent block has BaseFee != nil to tell whether we are using London txs. This then updates the GasTipCap and GasFeeCap. GasFeeCap is then used to later when generating a new tx to see whether it should be a LegacyTx or a DynamicFeeTx.

There is also a dependency upgrade for go-ethereum to v1.10.6

Go aside, the logic makes sense. Also for reference this is what we do in web3.js
