This trait is eval-specific, there's no point in dealing with these
things in tvix-store.
This implements the EvalIO interface for a Tvix store.
The proper place for this glue code (for now) is tvix-cli, which knows
about both tvix-store and tvix-eval.
There's one annoyance with this move: The `tvix-store import` subcommand
previously also used the TvixStoreIO implementation (because it
conveniently did what we wanted).
Some of this code had to be duplicated, mostly logic to calculate the
NAR-based output path and create the PathInfo object.
Some, but potentially more of this can be extracted into helper
functions in a shared crate, and then be used from both TvixStoreIO in
tvix-cli as well as the tvix-store CLI entrypoint.

There was a NixHash::new() before, which didn't perform any validation
of the digest length. We had some length validation when parsing nix
hashes or SRI hashes, but some places didn't perform validation and/or
constructed the struct directly.
Replace NixHash::new() with a
`impl TryFrom<(HashAlgo, Vec<u8>)> for NixHash`, which does do this
validation, and update constructing code to use that, rather than
populating structs directly. In some rare cases where we're sure the
digest length is correct we still populate the struct manually.
Fixes b/291.

Some paths might use names that are not valid UTF-8. We should be able
to represent them.
We don't actually need to touch the PathInfo structures, as they need to
represent StorePaths, which come with their own harder restrictions,
which can't encode non-UTF8 data.
While this doesn't change any of the wire format of the gRPC messages,
it does however change the interface of tvix_eval::EvalIO - its
read_dir() method does now return a list of Vec<u8>, rather than
SmolStr. Maybe this should be OsString instead?

This is a first implementation of a FUSE filesystem, mounting tvix-store

This is mostly meant as one additional lens into a store, and could be
used for builds. It's not meant to be used as a general-purpose thing.
It still has some rough edges:
- It doesn't implement open/close, so it doesn't use file handles.
Which means, we need to open blobs for partial reads over and over
again.
- It doesn't implement seek, as BlobReader doesn't implement seek yet.
- It doesn't track "lifetimes" of inodes by listening on forget,
meaning it might hold more data in memory than necessary.
- As we don't have store composition (and a caching layer) yet,
operations might be slow.
