Implement SCL/KBM Tuning in Dexed

This commit implements SCL/KBM tuning in Dexed, using essentially
the same tuning code as surge, and includes

- SCL/KBM parsing
- Moving the frequency resolution to a managed class
- UI changes to show and correctly operate the param window
- Transposition traps for +/- 12,24 in tuned modes
- Support for drag n drop of KBM/SCL
- And a variety of small changes to make tuning usable
