Major Changes

Optionally filter Sonarr sync by series type - e.g. anime, daily, or standard via series_type sync argument (#305)
Significantly improve start-up speed by modifying API calls to Sonarr

Major Fixes

Handle Preference files with neither emby or plex sections
No longer ignore blacklist threshold for source image selection
Much stricter matching of episodes to TMDb movies
- Some false-positive matches could occur if the episode were unaired and of a relatively "common" title
- Matches now require TMDb ID match or a perfect title match and the airdates match (±1 day)

Allow for .webp image extensions (#84)
Support format strings in index and absolute episode ranges (were only supported in season titles), i.e.:
```
episode_ranges:
  s1e1-s1e4: Episode {episode_number}
```
Allow filtering of sync with required tags via (previously Sonarr-exclusive) required_tags argument (#308)
- This utilizes the Sharing Labels field set within Plex:
- This utilizes the Tag field within Emby
Added --revert-series argment to fixer.py to "remove" a series' title cards from Plex (#303)
- Specified like fixer.py --revert-series "TV Shows" "Breaking Bad" 2008 - i.e. {library} {show name} {year}
Added --media-server argument to fixer.py to select between Emby/Plex media servers for fixer operations
