Add a mechanism to map a response from a side effect

[dacanizares]

Current sample:

await
    from maybeBicicleta in
        from bicicleta in _repository.FindByIdAsync(id)
        select _mapper.Map<CompleteBicicletaViewModel>(bicicleta).AsMaybe()
    select maybeBicicleta.Match<IActionResult>(Ok, NotFound());

Expected to be used like:

await 
    from maybeBicicleta in new Maybe<int>(id).AwaitSideEffect(_repository.FindByIdAsync)
       // Add Map overload that works with Maybe
       from _mapper.Map<CompleteBicicletaViewModel>(maybeBicicleta)
    select maybeBicicleta.Match<IActionResult>(Ok, NotFound());
