This provides a service using /dev/shm, that's deleted once the

Refactor all tests to use these, which allows getting rid of most
TempDir usage in the tests.
The only place where we still use TempDir is in the importer tests,
which work on a filesystem path.

This switches away from the less canonical "ronomon" version to the
implementation as described in the
[paper](https://ieeexplore.ieee.org/document/9055082) by Wen Xia, et
al., in 2020.
That version uses 64-bit hash values and tends to be faster than both
the ronomon and v2016 versions, and produces the same chunking as the
2016 version.
As per https://docs.rs/fastcdc/latest/fastcdc/#implementations-1, it's
the recommended choice.
The crate also gained support for streaming version of chunkers:
https://docs.rs/fastcdc/latest/fastcdc/#large-data, which might be
useful.

root of a (store) path, and writes the contents in NAR serialization to

We need this in various places:
- tvix-store's calculate_nar() RPC method needs to render a NAR stream
to get the nar hash, which is necessary to give things imported in
the store a "NAR-based" store path.
- communication with (remote) Nix (via daemon protocol) needs a NAR
representation.
- Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a
NAR representation.
