audio/fasttracker2: Update to 1.89

Changes since 1.88:

v1.89 - 07.12.2024
- Fixed a possible crash on macOS (and possibly Linux) when loading a module
  whose filename includes special non-ASCII characters.
- Added a "Default audio device" option when selecting input/output audio
  devices in the config screen. This option has a few edge-case bugs, though.
- Added an experimental Impulse Tracker module loader. This should only be used
  to extract patterns/instruments/samples, as there are severe conversion errors
  when this format is converted to XM under load.
  WARNING: This loader has not been thoroughly tested, and may cause a crash!
- Fixed a bug with the tracker scopes where the sample would sometimes not be
  displayed correctly during a sample/note trigger.
- Replaced the Gaussian (SNES) interpolator with a 6-point cubic Hermite option.
  The Gaussian interpolator was very niche anyway, and as it sounded quite
  filtered, I think the vast majority of users wouldn't see a use for it.
- Added a few missing Norwegian/Danish alphabet letters to the main font (code
  page is now 850 instead of 437).
- Show extra digits (when space for them) in the C-4 Hz string in the instrument
  editor screen.
- Again, slightly improved the interpolation method for the tracker scopes in
  "Lined" mode (when using the cubic/sinc interpolators).
- Slightly increased the contrast for the sample editor's loop pin lines
