Surface closures and light sampling now take both shading and geometric normals.
...
This will allow them to appropriately handle weirdness that comes
from the shading normal and geometric normal being different.

Bunch of code quality improvements based on running clippy.
...
None of them change behavior, just make the code cleaner.

Split colorspace transform functions out into their own crate.
...
They are now generated by a build.rs script from nothing but the
colorspace's primaries, which makes it super easy to add more
colorspaces. So easy that I added three more: ACES AP0, ACES AP1
and Rec.2020.
This lays the foundation for supporting output to different
colorspaces.

Fixed a bunch of problems that came up when running debug build.
...
The worst offender was an obvious and nasty bug in the bitstack
implementation. Hooray for debug asserts!

Fixed bug in GTRClosure that was resulting in all NaN outputs.

Added GTR surface closure.
...
Not tested yet, just a straightforward conversion from the C++
Psychopath codebase. So there are probably bugs in it from the
conversion. But it compiles!

LightTree now works with lights in hierarchical instancing.

Code cosmetics: organize and alphabetize crate/mod/use statements.

Implemented light tree sampling, for better sampling of many lights.

Got rid of indexing into Float4 and 3d vector elements.
...
This assures correct semantics for SIMD usage.

Make renderer actually use the material system properly.
...
The intersection code still isn't using any kind of shading,
and materials aren't parsed by the parser, but the renderer
class itself is using them.

Fixed bugs in global illumination.
...
It was a stupid thing in the Lambert closure. It was returning
the wrong direction vector.

Beginnings of global illumination.
...
There are still some obvious bugs in it that I haven't tracked down,
so the renders aren't correct yet.
