API for getting the paths of a dataset

[normanrz]

Detailed Description

For integration of virtual datasets with the worker and voxelytics, we need an API endpoint that returns the paths of the mags and attachments of a dataset.
In the wklibs, I could imagine an additional argument for Dataset.open_remote:

ds = wk.Dataset.open_remote("https://webknossos.org/datasets/...", resolve_paths=True)
assert ds.get_layer("color").get_mag(1).path.protocol == "s3"
