Editor: pause the Device-audio heartbeat during a firmware push

Browse source 
Push advanced to ~150/506 chunks then stalled intermittently. With Device audio on, the
heartbeat (0xFE every 250ms + a clock SysEx every ~3s) shares the MIDI link with the
firmware chunks and intermittently costs a chunk its ACK. Pause the heartbeat for the
duration of _pushFirmware and resume after.
