Add 'methodId' field to NormalTx structure

[tergrif]

Etherscan API Normal Transfers json response contains also the "methodId" field
(https://docs.etherscan.io/api-endpoints/accounts#response-7)
,which is missing in NormalTx struct. I have added it in code (locally) and it works,but I guess it needs to be formal (if you want to,of course),but I don't understand too much the mechanics of pull requests and merge approvals here

Hi,

Sure, contributions on missing fields are always welcome!
To create a pull request, you may refer to the guide https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request
If it's not feasible, I can take over the editing effort during my free time.

Thanks for the hands-up!
