Attached patch makes _sre.compile() more strict on types: groupindex must be a dictionary and indexgroup must be a tuple.

Currently, indexgroup is passed as a list. I chose to convert it to a tuple to use less memory and to prevent unwanted changes. For unwanted changed, I'm not sure because groupindex remains a mutable dictionary. Do you think that it's worth it to require a tuple? Another option is to accept a list but to convert it to a list, but this change is more specific to the current implementation.
