monomeSC 250331 (v 1.8)

new

functionality now split across one main Monome class and two subclasses (MonomeGrid and MonomeArc)
Monome class handles serialosc communication and device meta-management
MonomeGrid subclass handles connectivity to connected monome grid devices, and should be a direct drop-in replacement for any previous monomeSC sketches
MonomeArc subclass handles connectivity to connected arcs
- this subclass includes a helper for setting per-encoder sensitivity (.setSens)
- rather than draw LEDs with a Routine (like MonomeGrid), the arc subclass employs a .refresh method to draw queued LED messages -- this keeps consistent with norns and iii scripting practices
