RESPDecodeError: Version 2

[adam-fowler]

See #225

I made an attempt at this a while back but it was decided not to merge as the error type didn't contain enough information. Preferably it would contain a stack of labels to show what you were decoding. We still don't have that but this time the error is extensible such that we can add it later if needed.
