add cossin LUT
 2020-12-10 17:02:03 +01:00
Robert Jördens 77cb0bbad0 cossin: refactor and tweak 
* shrink the LUT by another bit
* correctly use the octant bit to offset the dphi to LUT entry midpoint
* add more diagnistics to the unittest and rewrite it in relative units
* MSB-align phase and output to match the PLL data, dynamic range and
  remove the need for roudning bias.
* clean up the build.rs table generator a bit
