in chroma LUT generator, fixed boundary issue

* previously, we were generating a chroma table where luminance was in [0, 100)
* now our table has bounds of (hue in [0, 360]) and (luminance in [0, 100])
* not going all the way to H=360, and L=100 didn't affect accuracy in practice, but it looked 'wrong'
