Add break and "idle clocks" commands
Break sends a break command. It has 16000 recovery cycles as per the existing GPIO based driver, though that might be unnecessary in practice. "idle clocks" sends up to 255 clocks with data line held high, and can be used to flush things out for example after changing the send delay, or before sending a DPOLL command as some CFAMs seem to require extra clocks there.
