Create a standard way to treat logs.

[luizstacio]

Today on the SDK, we have some places using logger from @ethersproject and others using plain console.log. We should make a standard and fix all places to use the same.

I think we should use logger (or equivalent) over console.log

I think this can be closed @luizstacio / @Torres-ssf , see:

• refactor: using FuelError instead of @ethersproject/logger #1278
• Error handling: what to do with @ethersproject/logger? #1207

Agreed - closing it.

@luizstacio Please reopen if you think something else is still required.
