Right now we cannot run tests automatically on github, because the backend has no GPU support

OptiX supports compaction of the acceleration structures that we don't use. We should use it.
Currently we only use GPU 0 for OptiX, but that need to change. We should pass to init the device on which we want to operate
We need conda packages for this repo. @ianthomas23 looking into this.
I have a use case, where I want to calculate hit distance to a mesh from a pinhole camera. Is there any examples of using rtxpy to do something like this?
We need to be able to handle more complex scenes, with multiple objects inside, Right now we only support single GAS scenes, but we need to build IAS that supports multiple.
Prepare to make a formal Python release
Right now there is only one global GAS for OptiX and if the user tries to build a second one we overwrite the first.
We need to add support for multiple GASs
OptiX works with both CUPY and NUMPY buffers, while CUPY is handled natively, Numpy can't so we allocate a GPU buffer to copy the numpy pointer into, then run the calculations on the GPU buffer, and then we transfer the results back to the numpy pointer. While this kind of workflow is expected, I've noticed that numba produces a user-facing warning that this usage results in an unnecessary overhead. Maybe we should produce such a warning as well.
