ADC: randomise the sampling rate
...
this is based on suggestions from Kari and Mike, and should reduce the
aliasing effects we get from the simple averaging

ADC: the bottom 3 bits of ADC output are always zero
...
its a 12 bit ADC .... silly of me to think the bottom 3 bits are
valid!

change ADC sample rate to 1kHz
...
this costs us about 9% of our CPU, but should make aliasing much less
of a problem.

ADC: re-work for ADC code for full resolution and accurate timing
...
this changes the ADC code to return the full resolution of the
sensors. It also adds a new Ch6() interface that returns 6 channels at
once, so the IMU can read 3 accelerometers and 3 gyros at once, and
get the exact time that the values were accumulated over
