Unifi-protect-backup

Fixed
- Event type enum conversion string was no longer converting to the enum value, this is now done explicitly.

Added
- Command line option to skip events longer than a given length (default 2 hours)
- Docker image is now based on alpine edge giving access to the latest version of rclone
Fixed
- Failed uploads no longer write to the database, meaning they will be retried
- Fixed issue with chunked event fetch during initial ignore of events
- Fixed error when no events were fetched for the retention period

Fixed
- Errors caused by latest unifi protect version by bumping the version of pyunifiprotect used
- Queries for events are now chunked into groups of 500 which should help stop this tool crashing large
unifi protect instances.

Fixed
- Time period parsing, 'Y' -> 'y'

Fixed
- Queued up downloads etc now wait for dropped connections to be re-established.

Fixed
- Missing event checker ignoring the "ignored cameras" list
