add a `__contains__` to Records

[nhumrich]

Since records work like dictionaries (record['my_column']), it would be awesome if the in operator worked. Would it be possible to add a __contains__ method to a record?

I was going to submit a PR with this, but for the life of me I cant find the record object, I think it might be implemented in C

Good idea! I'll do it.

Yes, it's implemented in pure C in asyncpg/protocol/record/recordobj.c.
