asyncpg v0.22.0

A new asyncpg release is here.

Notable additions include Python 3.9 support, support for recently added
PostgreSQL types like `jsonpath`, and last but not least, vastly
improved `executemany()` performance.  Importantly, `executemany()` is
also now _atomic_, which means that either all iterations succeed, or
none at all, whereas previously partial results would have remained in
place, unless `executemany()` was called in a transaction.

There is also the usual assortment of improvements and bugfixes, see the
details below.

This is the last release of asyncpg that supports Python 3.5, which has
reached EOL last September.
