Add runCatchingResponse

[freya022]

This should allow users to run code which throws certain error responses

The top level function should return Result<Unit> as we cannot recover any data, extensions to Result<Unit> will "recover" the Result (suppress the exception), while still wanting to use Result#getOrThrow to notify the caller of unrelated exceptions

The goal would be to somewhat replicate JDA's ErrorHandler, typical use case is sending a DM, while handling/ignoring only CANNOT_SEND_TO_USER and rethrowing other exceptions/error responses
