`VectorDataset.__getitem__`

This approach makes sense to me. We primarily care about `bbox_xyxy` since that's what our `ObjectDetectionTask` currently focuses on. > Though I still have some problems with dataloaders and `collate_fn`...

For instance segmentation, our `InstanceSegmentationTask` trainer currently uses Mask R-CNN, so it should be in a compatible format. See how VHR-10 does it, we want to use the same syntax.

I know pickling doesn't work (which means multiprocessing doesn't work on macOS/Windows): #87

Unfortunately this didn't work. The code failed on [this line](https://github.com/bazelbuild/bazelisk/blob/fec36a9bcfbf5076380fa129ef3ec21880c2fc4f/bazelisk.py#L239): ``` Traceback (most recent call last): File "/tmp/adam/spack-stage/spack-stage-py-tensorstore-0.1.54-qt43dqks2rfboadkdose2dbxwfl5u47w/spack-src/bazelisk.py", line 492, in sys.exit(main()) File "/tmp/adam/spack-stage/spack-stage-py-tensorstore-0.1.54-qt43dqks2rfboadkdose2dbxwfl5u47w/spack-src/bazelisk.py", line 477, in main bazel_path =...

Wonder how much of the build systems stuff duplicates/repeats https://spack.readthedocs.io/en/latest/build_systems.html. I agree that there is a natural split between directives and functions, and that the current Packaging Guide is too...

Progress so far: ``` > mypy Found 669 errors in 69 files (checked 108 source files) > mypy --strict Found 4476 errors in 95 files (checked 108 source files) ```

Most issues so far are trivial, but tedious.
