Non-aerospace rotation sequence

With pitch and roll calculated using nonaerspace rotation sequence.
Roll angle does not flip signs when it reaches +- 90, however it is
desensitized with increasing pitch angle.  This means that if kids set
their thresholds in a horizontal position, they might not be able to
reach them with arm at other pitch angles.

Benefit is that the roll angle does not change significantly with pitch
angle.

Downside is that the roll angle changes signs at +- 90, which causes it
to switch between supination/pronation.  I added extra conditionals to
combat this, but now extreme pronation (past 90 degrees) reads as
neutral (I included a sketchy fix that seems to work)
