audio/fasttracker2: Update to 1.66

Changes since v1.65

v1.66 - 13.04.2023
- Added a 16 point sinc interpolation option (higher quality)
- Changed some settings for the default configuration:
   1) Palette theme = Dark mode
   2) Scopes = Lined
  Note: Your existing configuration will not be changed!
- Changed the layout a little in the Config section (Audio / "I/O Devices")
- Removed the 192kHz audio output setting. This was a bit extreme to begin with.
  Note: You can still select this rate when exporting songs to WAV.
- Some code cleanup
