Variable shadowing from OUSD to ERC20.md

135 - Variable shadowing from OUSD to ERC20

OUSD inherits from ERC20, but redefines the allowances and _totalSupply state variables.

As a result, access to these variables can lead to returning different values.

Recommendation:

Remove the shadowed variables (_allowances and _totalSupply) in OUSD.
