Live retuning, recording file names, bug fixes

• New: Add live-retuning capabilities
  • In the past, microwave always used Single Note Tuning Change messages to retune external synthesizers
  • With the newest version the tuning method (--tun-method) can be full, octave, channel or pitch-bend
• Improvement: You can now specify the file prefix for wav recordings using the --wav-prefix parameter
• Bug fix: The scale degree offset was rendered with the wrong signum (+ instead of - and vice versa)
• Bug fix: The default-envelope indicator wasn't rendered correctly

Physical modeling synthesis, more waveforms

• New: Flexible waveguide model
  • Allow any input buffer to serve as a waveguide exciter
  • Support positively or negatively reflective waveguides
  • Add a non-linear limiter function for more realistic waveguides and to avoid over-excitation
• New: Add more physically modeled default waveforms
• New: Add StageSpec::Signal / SignalKind::Noise
• Improvement: Add LfSourceUnit::Wavelength

Custom envelopes, arbitrary number of waveform buffers

• New: Define custom envelopes
  • Envelopes are defined in a separate section of the waveforms file
  • Envelopes can be applied to almost any parameter using LfSource::Envelope
• Improvement: Support any number of waveform buffers
  • The number of buffers was previously restricted to 2
• Improvement: Simplify the waveforms file format

No functional changes, make it compile again

• Change: Update dependencies s.t. microwave compiles with Rust 1.51

Minor API changes

• Change: Return orig_key in TransformResult
• Change: the ChannelMessageType::PitchBend variant now uses i16 instead of u16

Fix live-retuning bug, named MIDI devices

• Bugfix: Fix live-retuning bug
  • Track keys by original key instead of the mapped note
• Improvement: Identify MIDI devices by name and not by index

Named MIDI devices, no-audio mode

• New: Add no-audio mode to use microwave as a pitch monitor only
• Improvement: Identify MIDI devices by name and not by index

More tuning theory, minor improvements

• Improvement: Calculate the errors and badness of a Val
• Improvement: Improve the error structs and the documentation of the scala module
• Change: Move ChannelMessage::transform to ChannelMessageType::transform for consistency

More tuning theory, better diff command

• Improvement: Calculate the errors and badness of an equal-step tuning
• Improvement: Make the diff command consistent with the remaining commands

Full KBM model

• New: Define and import keyboard mappings via microwave ref-note or microwave kbm-file
