Release v1.7.3

• Performance: Improved startup time.
• Settings: Added an option to disable automatic recording when a game is detected (#219).
• Recording: Added support for Discord Canary and Discord PTB as detectable voice chat apps. Thanks @Guibibi!
• Upload: Raised the default "copy as compressed" size from 10 MB to 20 MB to match Discord's new upload limit.
• Upload: Included the game's executable filename in upload metadata.
• Startup: Fixed startup failures when the configured recording or cache folder is unreachable (for example an unmounted drive) by falling back to the default folder and notifying the user.
