feat: unify data IDs

[floryst]

Volume keys are now used as image data IDs. This simplifies going back and forth between the image and dicom store, and simplifies the structure of the selection object to be just an ID string.

This doesn't address migration of older session files. That is a nice-to-have, but we don't have a good way of handling migrations at the moment. @PaulHax if this breaks stored session files, then I'll add a migration path.

So nice. Does break loading old session files with layers due to the dropping of the gross image/dicom prefix on the layer IDs. But I'm OK with that.

We can figure out a migration layer later if this becomes a major issue. For now, I've bumped the manifest major version.

When/if we get a complaint, we have some migrate code here:

VolView/src/io/import/processors/restoreStateFile.ts
