Summary: Avoids use of `torch.cat` operation when rendering a volume by instead issuing multiple calls to `torch.nn.functional.grid_sample`. Density and color tensors can be large.

Summary: new implicitronRayBundle with added cameraIDs and camera counts. Added to enable a single raybundle inside Implicitron and easier extension in the future. Since RayBundle is named tuple and RayBundleHeterogeneous is dataclass and RayBundleHeterogeneous cannot inherit RayBundle. So if there was no ImplicitronRayBundle every function that uses RayBundle now would have to use Union[RayBundle, RaybundleHeterogeneous] which is confusing and unecessary complicated.

Summary:
Added heterogeneous raysampling to pytorch3d raysampler, different cameras are sampled different number of times.
It now returns RayBundle if heterogeneous raysampling is off and new RayBundleHeterogeneous (with added fields `camera_ids` and `camera_counts`). Heterogeneous raysampling is on if `n_rays_total` is not None.

Summary:
pyfmt now specifies a target Python version of 3.8 when formatting
with black. With this new config, black adds trailing commas to all
multiline function calls. This applies the new formatting as part
of rolling out the linttool-integration for pyfmt.
