Allow specifying the mask and bbox keys in the GraphArrayView

[cmalinmayor]

We want to store two masks for each cell - the whole membrane and the nucleus segmentations - and display them both as GraphArrayViews in napari. This edit should keep the default behavior of "mask" and "bbox" if not specified, but allow you to specify.

Is there anywhere else in the repo where a single mask and bbox per node is assumed that I should be aware of to make sure I don't break any default behavior? @TeunHuijben @JoOkuma (tagging cause I can't request reviewers)

Second edit: immediately found more places when I tried to run a slightly different script, new commits coming 🙃

Force pushed to rebase onto rc3, so I can actually run tests without running into #294

[TeunHuijben]

@cmalinmayor, let's try this on your side without the rebase, but using the latest tracksdata release, and funtracks main

@cmalinmayor, I'm returning from vacation. Sorry for the late reply.

Multiple masks should definitely work, as long as you provide the correct non-default attribute name when displaying the alternative masks.

I'm going to Janelia on Jun 11th, happy to team up and help with any other issues you're having.

Provide them where? The defaults are currently hard-coded into the GraphArrayView on main, which is what this PR changes.

Definitely! I'm finally diving deeper into the tracksdata world, and I think I can have more intelligent questions now. Would love to pair program a bit while you are here.

Agreed, your PR is necessary.
