audio/fasttracker2: Update to 1.93

Changes since 1.92:

v1.93 - 24.12.2024
- .S3M loader bug fix: The Axx (Set Speed) effect broke in v1.89. Oops..!
- .IT loader: Fixed behavior for overflowing sample offset effect, and illegal
              portamento slides (still somewhat wrong, but better than before).
              Not that you should use the FT2 clone for playing .IT files!
