Separate Synth and SynthState: SynthState is the part that Render changes.

Browse Source 
This should make testing easier, as Synth can be assumed to stay the same
during each call. Synth is also the part that we can parse from .asm/.json file
and a Patch can be compiled into a synth. Synth can be eventually made
quite opaque to the user. The user should not need to worry about opcodes
etc.
