This adds support to compute the fingerprint string, which is what's ed25519-signed in binary caches.

2023-11-19 r/7035 feat(nix-compat/nar/reader): provide passthrough buffered I/Oedef1-13/+75
Allow taking advantage of the buffer of the underlying reader to avoid unnecessary copies of file data. We can't easily implement the methods of BufRead directly, since we have some extra I/O to perform in the final consume() invocation. That could be resolved at the cost of additional bookkeeping, but this will suffice for now.

We rely on being able to make small reads cheaply, so this was already an implicit practical requirement. Requiring it explicitly removes a performance footgun, and makes further optimisations possible.

This specific struct is only used to represent content-addressed paths (in case a Derivation has a fixed-output hash, for example). Rename `Output`'s `hash_with_mode` to `ca_hash`. We now also include `CAHash::Text`, and update the `validate` function of the `Output` struct to reject text hashes there. This allows cleaning up the various output path calculation functions inside nix-compat/src/store_path/utils.rs, as they can now match on the type. `make_type` is renamed to `make_references_string`, `build_regular_ca_path` is renamed to `build_ca_path`, and `build_text_path` has a disclaimer added, because you might not actually want to use it.
