audio/fasttracker2: Updates to v1.44

Changes since v1.43

v1.44 - 01.03.2021
- The second "Key Off" key (key next to left shift) didn't work on all \ 
keyboard
  layouts.
- Added support for importing DIGI Booster (non-Pro) modules
- Added support for importing 8-channel StarTrekker modules
- Removed calculation of some big tables because they were not really that
  important for performance after all, and also made the video/audio sync data
  more compact. Saves around ~1.8MB of RAM. Not a whole lot, but still nice.
- Code refactoring in module/sample loaders. It's easier to add new loaders now!
- Minor code cleanup and code change
- Updated help text
