Summary:
We need to make packing/unpacking in 2 places for mixed frame raysampling (metrics and raysampler) but those tensors that need to be unpacked/packed have more than two dimensions.
I could have reshaped and stored dimensions but this seems to just complicate code there with something which packed_to_padded should support.
I could have made a separate function for implicitron but it would confusing to have two different padded_to_packed functions inside pytorch3d codebase one of which does packing for (b, max) and (b, max, f) and the other for (b, max, …)

Summary:
Added export of UV textures to IO.save_mesh in Pytorch3d
MeshObjFormat now passes verts_uv, faces_uv, and texture_map as input to save_obj

TODO: check if TexturesUV.verts_uv_list or TexturesUV.verts_uv_padded() should be passed to save_obj

IO.save_mesh(obj_file, meshes, decimal_places=2) should be IO().save_mesh(obj_file, meshes, decimal_places=2)

Summary:
A significant speedup (e.g. >2% of a forward pass).

Move NDCMultinomialRaysampler parts of AbstractMaskRaySampler to members instead of living in a dict. The dict was hiding them from the nn.Module system so their _xy_grid members were remaining on the CPU. Therefore they were being copied to the GPU in every forward pass.

(We couldn't easily use a ModuleDict here because the enum keys are not strs.)

Summary:
The self._stratified_sampling attribute is always overridden unless stratified_sampling is explicitly set to None. However, the desired default behavior is that the value of self._stratified_sampling is used unless the argument stratified_sampling is set to True/False. Changing the default to None achieves this

Summary: On each call of the stats.update the object calculates current average iteration time by getting time elapsed from the time_start and then dividing it by the current number of steps. It saves the result to AverageMeter object which when queried returns the average of things saved, so the time is averaged twice which biases it towards the start value (which is often larger).

Summary: Currently some implicit functions in implicitron take a raybundle, others take ray_points_world. raybundle is what they really need. However, the raybundle is going to become a bit more flexible later, as it will contain different numbers of rays for each camera.
