trig/atan2: refine
...
* use dynamic scaling of the inputs to get accurate ratios (effectively
floating point) to maintain accuracy for small arguments
* this also allows shifting later and keep more bits
* use u32 ratio to keep one more bit
* merge the corner case unittests into the big test value list
* print rms, absolute and axis-relative angle
* simplify the correction expression to get rid of one multiplication
* use 5 bit for the correction constant and 15 bits for r
* least squares optimal correction constant, this lowers the max error
below 5e-5

207: atan r=jordens a=matthuszagh
Adds 2-argument arctangent function. Parameters and result are `i32` integers for fast computation. Only the 16 MSBs of the inputs are used (16 LSBs are discarded). The x and y inputs can range from -1 to 1, which corresponds to `i32::MIN` and `i32::MAX`, respectively. The output ranges from -pi to pi, which corresponds to `i32::MIN` and `i32::MAX`, respectively.
