Add support for UniFi Video >= 3.2.0

Unfortunately, Ubiquiti changed their (supposedly versioned) API in
3.2.0 which causes us to have to refer to cameras by id instead of
UUID. The firmware for 3.2.x also changed the on-camera login procedures
and snapshot functionality significantly.

This bumps the requirement for uvcclient to 0.9.0, which supports the
newer API and makes the tweaks necessary to interact properly.
