can't make From<M::Error> because it potentially conflicts with blanket From<T> for T in cases where M::Error and ContractError<M> are the same type
yes this is weird

Yeah, this would be fixed with specialization, but alas

Outdated

deliberately broken 3rd party direct instantiation, so that users must use the from_middleware_error method
similar for provider error. broke it to force From usage

@prestwich That's fine since you're integrating it with the general Contract error, my PR was mostly about having a better API for the multicall call methods
Motivation
Users don't have access to revert data. That sucks. I'm fixing it.
