Fix colorspace illuminant, LayeredBxDF transmittance, and film pixel bounds
...
- from_interleaved ignored its arg, so D65 came from a separate
hand-normalized table that was scaled to luminance 1 instead of
CIE_Y_integral and mapped to 300nm when it starts at 360nm. sRGB
rgb_from_xyz came out ~120x too large with the wrong white point, making
every render ~120x too bright with a colour cast. Now built as pbrt does:
from_interleaved(&CIE_ILLUM_D6500, true).
- LayeredBxDF::Tr: puts the minus on the result,
not the exponent, so transmittance was negative and grew exponentially.
killeroo-coated-gold went from 15 Infs / min -4168 / stddev 638 to clean.
- layered.rs used Float::MIN where C++ has numeric_limits<Float>::min(). Those
differ: the latter is f32::MIN_POSITIVE. Both guards were dead, leaving a
zero thickness to divide by.
- FilmBase::create expanded pixel_bounds by the filter radius. pbrt never does;
the radius widens SampleBounds() only. Output was 1372x1030, not 1368x1026.
- Gate the ENQUEUE/DEQUEUE wavefront prints behind cpu_debug; their queues
reset every depth/batch/sample so they fired constantly (100h renders).

This commit is way too large. So, added Upload trait back again, but only for Textures, which are the most complex types. Fixing Medium and PixelSensor creation on host side. Can´t really find a satisfying way of keeping construction and creation separate, so for now, regrettably, putting them in the same place. Added some types to parameter parsing.
