Resolves #152: VolumeCache used to be set up to store arbitrary volume subsets, but is now used to represent a fixed set of volume chunks. We're not likely to ever use the more "advanced" dimension-aware indexing again, so there's no point keeping it around.
This PR changes VolumeCache to just index entries by string keys, updates loaders to get and insert using string keys, and updates tests.
