Add/update oracles to retrieve the price

[moisses89]

What is needed?

Currently safe-eth-py have several oracles implemented to retrieve the price from them but the last update of them was on October of 2021.
I would like to review the oracles implemented to check if new versions of contracts are deployed eg: UniSwapV3, and research if we can add some more new oracles.

Background

The focus of this issue is add more opportunities to retrieve the price from decentralized options before centralized options.
