AIP - 67: Change oracle implementation for bIB01

Hey everyone,

This is a proposal to change the oracle for the bIB01.

Context

The bIB01 was recently deployed as a collateral for agEUR on mainnet. The oracle implementation used was a custom implementation maintained by Backed.

Chainlink recently deployed an IB01-USD feed (at the address: 0x32d1463EB53b73C095625719Afa544D5426354cB).

Proposal

Given that Chainlink is the trusted solution used everywhere in Angle contracts to secure price feed, proposal here is to switch the IB01 oracle implementation from Backed version to Chainlink version.

Implementation

This requires deploying a new oracle contract (with as a reference the new IB01 price feed).

Value to the protocol

Intent is to make the oracles used by the protocol safer, and not rely on another third party (here Backed dev team) when it comes to the oracles.

Voting Options

1. For, change oracle
2. Against, do nothing
