Plex-mpv-shim

This update provides a fix for remote control of the menu.

This release contains both bug fixes and new features. The new features are:
- Add support for subtitle color, position, and size settings.
- Show media title in interface and titlebar.
- Add new setting to locally limit bandwidth for remote direct play. (Disabled by default.)

Bug fixes:
- Ensure transcode sessions are properly created and terminated.
- Improve handling of subtitles transcodes.
- Remove legacy remote_transcode setting.
- Prevent tokens being printed to the console by default. (Configurable.)
- Properly clean up threads on exit.
- Only show mass subtitle update for episodes.

This version introduces the ability to play external subtitles. There are also some performance and reliability improvements. Specifically, the status of the player and user actions are less likely to freeze if a client goes offline or the Plex server is responding slowly to requests.

would be impossible to support through the remote control interface normally, such as:
- Change subtitle or audio tracks. The full titles from the media file are shown.
- Automatically change the subtitle and audio streams for an entire series at once.
- Adjust video transcoding quality without restarting.
- Change transcoding preferences without editing the config file.
- Quit the player, marking the current video unwatched.

The interactive menu supports both the keyboard and the remote control. To open the menu
from a phone, press the ok or home button. Press back to go back or close the menu. The
keyboard shortcut to open the menu is `c`. Use the arrow keys, escape, and enter/space
to navigate the menu.

Plex-MPV-Shim 1.2.0 introduces revamped transcoding support. It will automatically ask the server to see if transcoding is suggested, which enables Plex-MPV-Shim to play more of your library on the go. You can configure this or switch to the old local transcode decision system. It also now supports changing audio and subtitle tracks for transcoded video and avoids issues where playback could fail due to bandwidth limits.
