Added some test files for fixed point math.

Something definitely broke in cosine when I changed to smaller tables
(which shouldn't have sacrificed any accuracy). Need to investigate...

Initial pass at a 32-bit fixed point library.

- Generated cosine / sine tables, put them in PROGMEM

- Wrote initial quadratic interpolation cosine function.
... not safe to use yet, but it seems to work for non-edge
cases. Need to write a better way to test it.
