Add OSC message for Kamikaze
We currently don't have a way to create a 'kamikaze' synth via OSC. This MR implements a new message /satie/scene/createKamikaze
which will essentially call .makeKamikaze
. The advantage of this message over using /satie/scene/createSource
and giving it a _kamikaze
suffixed SynthDef is that it avoids cluttering up the groupInstances
dictionary with ephemeral synths.
