206eb4d591 clean up diagnostic more and make it more robust 
A number of changes:
- don't enable interrupts, since they often cause hangs (not sure why)
- remove GND measurement
- wait 100 us between AMUX setup and start of conversion, to let input
  settle
- reduce delay between line setup and samping from 100 ms to 50 ms,
  for this is already sufficient

2f82a4f306 tools/ant-cl/ant-cl.c: add diagnostic mode (-D); various RF comm improvements 
The RF communicaion improvements:
- separate ACK handling from packet(),
- pass ACK payload to caller,
- take reception timeout from callers,
- -d also dumps received packets.

also run on JLime. Graphical output is disabled so far.

a924364311 fw/rf.c (rf_send): increase delay from 2 ms to 9 ms, for slow atben 
Not sure why the Ben exhibited such a long turn-around time. It should
actually be faster than a PC with atusb. Maybe it's because of latency
introduced by other sources.

c9923b4282 fw/antorcha.c (main): allow a new sweep to preempt an active sweep

(without cancelling it), confusing the timing.

- remove struct params.clkT_period

Things now work a bit differently from how they were planned back when
clkT_period was added.

00180fb287 try cleaner sweep synchronization algorithm

use a fixed offset from the trigger.

695bc5a25a fw/: reduce image width from 100 to 80 square pixels 
To achieve square 100 pixels (1:6.25 image aspect ratio), very vigorous
movement is needed. 80 pixels (still 1:5) are easier. Initial estimates
suggested a usable range of 1:4-1:5, so this is still good.

Note that we may want to change the aspect ratio of the pixels themselves
in the future (for smoother letters), so the pixel count may go up again.

80 pixels correspond to 11 characters in a 7x5 font with 2 pixels
separation between characters. We may want to go up to 82 pixels
to allow a 12th character - or use a proportional font.
