sled, and one using a HashMap.

419f7d0f0c feat(tvix/store): add NARCalculationService trait and impl
This adds a NARCalculationService trait, which will take a root node,
and provide a proto::CalculateNarResponse in return.

It also adds a NonCachingNARCalculationService implementation, that will
simply always render the NAR in memory to calculate the size and sha256,
without any caching.

df3223fd68 chore(tvix/store): move NAR rendering logic into Renderer struct
This moves the logic rendering NARs to a struct using the
previously introduced, more granular BlobService, ChunkService and
DirectoryService.

Instead of passing them around to the helper functions, they're kept as
members of a struct.

Remove the async invocations in the nar_renderer tests, there's nothing
async in here.

69516f1f68 feat(tvix/store/blobservice): add GRPCBlobServiceWrapper
This takes a BlobService and ChunkService in the constructor, and
provides a [proto::blob_service_server::BlobService] trait for it.

Implementing proto::blob_service_server::BlobService is a lot of surface
to cover, and providing this wrapper will make individual
implementations taking care of how to store chunks or chunking
information much simpler.

87e1934f2d docs(store/protos): update comment on blobstore Read and Put
Further emphasize Read() can be used to ask for blobs OR chunks, and
that clients usually want to stat and then request (smaller) chunks,
rather than reading whole blobs.

Also clarify that the chunking used to send BlobChunks over has nothing
to do with the chunk sizes communicated in a Stat() request.

0db73cb2bd feat(tvix/store): add write_nar function
This adds a function that consumes a [proto::node::Node] pointing to the
root of a (store) path, and writes the contents in NAR serialization to
the passed [std::io::Write].

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.
