Release v0.0.7-alpha

The focus of this version has been bug fixes; in particular around loading Mirage libraries and presets.

• Max voice is increased from 32 to 256 allowing for more complex instruments
• Show the instrument type on the GUI: single sample, multisample or oscillator waveform
• Rename 'Dynamics' knob to 'Timbre' and fix its behaviour - for instruments such as Arctic Strings, it can be used to crossfade between different sets of samples.
• Fix missing code signing on Windows installer resulting in 'Unknown Publisher' warning
• Fix layer filter type menu being the incorrect width
• Fix crash when loop points were very close together
• Improve loop modes on GUI: it's obvious when a loop is built-in or custom, what modes are available for a given instrument, why loop modes are invalid.
• Add docs about looping
• Fix sustain pedal incorrectly ending notes

Mirage loading:

• Fix incorrect loading of Mirage on/off switches - resulting in parameters being on when they should be off
• Fix incorrect handling of Mirage's 'always loop' instruments
• Fix incorrect conversion from Mirage's effects to Floe's effects
• Improve sound matching when loading Mirage presets
• Fix failure loading some FrozenPlain Squeaky Gate instruments

Library creation:

• Re-organise the fields for add_region - grouping better into correct sections and allowing for easier expansion in the future.
• Sample library region loops now are custom tables with start_frame, end_frame, crossfade and mode fields instead of an array.
• Add always_loop and never_loop fields to sample library regions allowing for more control over custom loop usage on Floe's GUI.
• Show an error if there's more than 2 velocity layers that are using 'feathering' mode. We don't support this yet. Same for timbre layers.
