ERC4626 for Borrowable Assets - USDC to Aave on Polygon

[NikMidas]

We should create an integration of AaveV3-4626 for an USDC market on Polygon.
In order to display the supply apy of the aaveV3 4626 we need to call getReserveData on the Pool contract which is https://polygonscan.com/address/0x794a61358D6845594F94dc1DB02A252b5b4814aD#readProxyContract on polygon.
It returns the ReserveData struct which can be found here: https://github.com/aave/aave-v3-core/blob/master/contracts/protocol/libraries/types/DataTypes.sol
In that we want to pull the currentVariableBorrowRate.

This will than give us the borrow apy which we can multiply with all the assets that we deployed into the 4626.
This we can than add to the borrow apy of our market and divide it by the total supply of assets in the market to get the total supply apy.
