feat(tvix/store/nar): add read_nar method

Browse source 
This adds a function that can ingest a NAR file into a given
blob_service and directory_service, returning the root node.

Passing around the directory_putter is a bit annoying, but at least for
this linear "reading through a NAR" case, we don't need it to be clone
or sync.
