v0.0.2

• When notes are released and new notes are triggered, channel allocation will avoid reusing the released channels for as long as possible so that longer envelope releases have a chance to ring down.
• Bugfix: when no notes were being played, and there were rules with Low, High, Old, or New target, and their matching control events were received, then MPE Emulator could emit MIDI System Reset (0xFF) messages followed by garbage data bytes. Now MPE Emulator will only emit MIDI messages that it is supposed to produce.
