types package keeps additional functions: ParseUint256orHex, ParseBytes, ... Isn't it better to keep ParseUint64orHex inside types and remove it from common? Otherwise, ParseUint256orHex will be a part of types and ParseUint64orHex will be a part of common

Yes it would be better, however it is not possible because of this function:
https://github.com/0xPolygon/polygon-edge/blob/develop/helper/common/common.go#L83-L97 (it uses ParseUint64OrHex and it is not possible to move it to types package because of circular imports).

If you want, we could move all the other Parse* functions from the types to the common package. WDYT?
