AHRS code doesn't work

Moved AHRS SPI code to cubesat_SPI_bus_library and it stopped working
properly. Going to revert to old version. If that doesn't work, AHRS
might be broken

There are conflicts, I'm not sure what that means, so I'm messing around
trying to resolve them

please just commit
Everything quasi-working, 1d tester updated

The MDB communicates over SPI with the UNO, sets different duty cycles,
calculates speed and direction. AHRS is also talking to the UNO on the
same SPI lines (except slave select), and it works as long as you talk
to the MDB before the AHRS.

Updated the 1-d faulhaber motor test rig ( the one that looks like a
basket) to allow easy removal of the layers. Should be ready for
cutting.
