Many new features and improvements

• New: Add separate effects section to microwave.yml (formerly waveforms.yml)
  • Available effects: Echo, SchroederReverb, RotarySpeaker
  • All effects can be MIDI controlled or automated via LfSources
  • Multiple instances of the same effect category can be used
• New: F1..F10 keys trigger Sound1..Sound10 events
  • Those events can be used to control sound effects
  • Events are accessible through MIDI CCNs 70..79 (configurable)
• Improvement: Toggle wav recording via Foot events (CCN 4, configurable)
• Improvement: Control legato option via Legato events (CCN 68, configurable)
• New: Touchpad gestures trigger polyphonic KeyPressure events
• Change: Touchpad gestures no longer trigger Breath events
• Change: Vertical mouse movement always triggers Breath events (CCN 2, configurable)
• New: Add LfSourceExpr::Linear to remap values in the range 0..1
• Change: Velocity and KeyPressure are now waveform properties
  • They can be accessed in the same way as WaveformPitch and WaveformPeriod
  • Use LfSourceExpr::Linear to remap them to the desired range
• Deletion: LfSourceExpr::Envelope has been removed
  • This feature required knowledge about the press state of a key which is not available in all contexts (e.g. effects)
  • It will come back with a different design in a future release
  • It is still possible i.e. mandatory to define a final envelope for each waveform
• Internal: Upgrade oxisynth to 0.0.2
  • This includes bugfix PolyMeilex/OxiSynth#2
• Improvement: Facilitate handling of input sources with shifted MIDI numbers
• Improvement / change: The harm subcommand is now able to generate NEJI scales
  • e.g. tune scl harm 27 --neji 12
  • The [harm] --sub parameter has been renamed to [harm] -u (for utonal)
  • Default names are in JI chord notation (e.g. "JI scale 8:9:10:11:12:13:14:15:16")
• Change: The import subcommand has been renamed to scl-file in order to be consistent with other subcommands
