Moved separate functions in halton sampler inline into the match.
...
Doesn't really have much impact, but makes me feel better for some
reason.

Leaf triangle intersection now loops over triangles per ray.
...
This is the inverse of what was being done before, which was to
loop over all of the rays for each triangle. At the moment, this
actually appears to be a tiny bit slower, but it should allow
for future optimizations testing against multiple triangles at once.

Removed a timer from a hot loop, and fixed node-test stat.

Gives I small performance boost, and now ray/node tests are
actually reported correctly. Yay!

Move multiple-object logic out of BVH4.
...
This allows each part of Psychopath tp handle the logic in the
best way, instead of a one-size-fits-all approach.

Changed ray batch data access to be through methods.
...
This is (potentially) just temporary. It's to make it a bit easier
to play with data layout to see how that affects performance.

Initial implementation of Jakob 2019 spectral upsampling.
...
It has a slight color cast to it at the moment, I believe due to
incorrect color space conversions, not because of the upsampling
method itself. So Meng upsampling is still the active method
at the moment.

MicropolyBatch doesn't need to satisfy Surface trait.
...
Eventually the Surface trait will be changed to actually mean the
ability to be processed _into_ a MicropolyBatch. So it's ultimately
nonsensical for MicropolyBatch to implement it.

Added another color temperature based way of specifying color.
...
This uses a normalized version of blackbody radiation, so the
colors still vary but the brightness doesn't vary nearly as
wildly as with genuine blackbody radiation.
