Improve GetLogs function

[FournyP]

Hi,

I've improved the GetLogs function because some of mandatory parameters are not mandatory for the etherscan API (e.g: toBlock, fromBlock and topic).

I've also add missing parameter page and offset.

Tests execution:

Feel free to ask me any change in my codebase

Have a good day ;)

Hi, @FournyP , thanks for your contribution!

I would love to see it merged but we cannot alter an existed API.
I recommend to implement it as a new method GetLogsByAddr(or choose a name in your flavor).

Cheers.
