Macros - Step one of four (#1090)

This is the first step in implementing Macros in ShortCircuit.

This introduces unipolar macros which are only adjustable by a
knob in the UI, but which fully work, are renamable, are editable,
stream, and act as modulation sources.

The remaining parts not covered in this PR are

- Bipolar and Stepped macro support
- Exposing the macros as CLAP parameters
- Implement the PLAY screen not just the macro screen
- Smoothed applicatino as opposed to direct application of value
  from the various sources
