This adds an additional nar-bridge-pathinfo command.
It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.
It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.
It's one building component as soon as we have store composition (which
we currently don't, so don't use this).
It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.
