Summary: When harmonic embedding is used, we always cat its input onto its output before proceeding. Avoid an intermediate tensor by making the module do that for itself.

Summary:
Add custom layer to avoid repeating copied data for every ray position.
This should also save time in the backward pass because there are fewer multiplies with the weights.

Summary: We don't use gradents of sample_pdf. Here we disable gradient calculation around calling it, instead of calling detach later. There's a theoretical speedup, but mainly this enables using sample_pdf implementations which don't support gradients.

Summary:
Fixes mostly related to the "main" build on circleci.
-Avoid error to do with tuple copy from initializer_list which is `explicit` on old compiler.
-Add better reporting to copyright test.
-Move to PackedTensorAccessor64 from the deprecated PackedTensorAccessor
-Avoid some warnings about mismatched comparisons.
The "main" build is the only one that runs the test_build stuff. In that area
-Fix my bad copyright fix D26275931 (3463f418b8) / 965c9c
-Add test that all tutorials are valid json.
