6ff21374 - Split `puffin-cache` into Puffin-specific and generic utilities (#728)

Split `puffin-cache` into Puffin-specific and generic utilities (#728) This crate started off as generic caching utilities, but we started adding a lot of Puffin-specific stuff (like the cache buckets abstraction that knows about Git vs. direct URL vs. indexes and so on). This PR moves the generic stuff into a new `cache-key` crate.
