demo / test

with pickit2 programming working for the essential parts, it's time to
write a demo / test.  add this to staaplc:

this leads to 2 operation modes:
  * OFFLINE: generate .hex and .ss files to manually upload + connect
  * ONLINE:  don't save those files, but upload binary and stay connected

interface to online programming should be the same as hex file saving.

'upload-monitor is working now.  next: activate target + serial
pass-through.  the latter requires a circuit and some thought, so
leave it for later.
