Change to Title case convention

Group builder algorithm works forwards, builds more static info about each group.

Algorithms now iterate over groups first, then segments within the groups as necessary.

Diverging from hardware, allowing a group to have 2 active loop segments by holding each segment button individually rather than both together (or using abLoop mode)

Was abusing legacy match from when using a triangle oscillator for the light levels

Using simpler sine oscillators for flashing lights that can render with a phase offset.

Cleaning up warnings.
