1. Add bit clock monitor and abort frame reception if clock is lost.
...
2. Make frequency measurement better for integral modem case.
3. New test mode: raw waveform (for integral modem).

1. Change transmit frame format to include a space for header CRC, so
...
SIMH standard frame formatting works unchanged. The HCRC is still
generated, though.
2. Change MAC addresses to be random AA-00-03-xx-yy-zz values, with
even zz for the interface address and zz+1 for the framer address.
The address is generated from the Pico board unique ID. This is
necessary (at least on some platforms) to allow multiple framers to be
plugged in; apparently they enforce unique MAC addresses even though
the Ethernet standard does not require that.
