Add compatibility properties to Range; implement pep-484
This adds a bunch of properties to new PG Range class for compatibility
with other implementations, providing a more similar API to access
emptiness and bounds status.
The naming conventions here derive from PostgreSQL itself,
see https://www.postgresql.org/docs/9.3/functions-range.html .
pep-484 also implemented by Mike, as this is a pretty type-intensive
module.
