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
