[Feature] Support encoded data for a contract call

[qiwu7]

Fixes # .

Motivation

Current geth-sdk does not support passing in already encoded data to construct a contract call transaction. There are cases where the argument is a tuple, and the rosetta impl will not be able to correct encode. So we would want the caller to handle data encoding and pass in the already encoded data.

For example, in EAS, the attest method takes in a struct instead of a list of args like most of the other methods. There is no way to support such data encoding with a list of args as the input. This requires incursive parsing of the args to be able to properly encode it in rosetta.

Solution

Delegate the data construction to the caller.

please add the license for new file and add the corresponding test cases, IMO unit tests for the function should be good enough
