v2.6.0 - Bug Fixes & Shaders

This release fixes a bunch of bugs and adds some new upscalers which in my testing
perform better than the old "generic" profile for all media types.

• Disable built-in MPV playback resuming. (#323)
• Support IPv6 addressing with a protocol prefix (#306)
• Switch to mpv build 20230304 362256e with TLS 1.3 support.
• Fix DEL stock MPV shortcut. (#326)
• Fix endless video skipping with auto profiles. (#323)
• Update Shader Packs to add NVIDIA Image Scaling and AMD FidelityFX shaders.
  • See release notes for details.
