L2 Public Client: estimateRelayMessageGas

[wilsoncusack]

OK so actually there's probably a subtask here that is estimateRelayMessageGas which would proxy to estimate gas from viem but set the caller to 0x0000000000000000000000000000000000000001, which is an address that will cause the function to revert if it is not relayed correctly.

from #55

I worked on this but not sure is worth doing given changing the from address makes a lot of transactions revert. Ie they need a specific msg.sender.

going to close for now

Actually, if you're using the crossChainMessenger then it shouldn't ever really matter who msg.sender is? The sender on the call to the contract is always going to be the crossChainMessenger? Probably still worth having. Thoughts @zencephalon @roninjin10 ?
