Florian Klink 98c17147c6 refactor(tvix/nar-bridge): have Export return root node 
… and nar size / sha256 digest.

Instead of producing sparse PathInfo messages when NARs are sent to
nar-bridge, the nar-bridge http server now keeps a lookup table
(narsha256) -> (rootNode, narSize)

This removes a whole bunch of noise, because we don't need to keep
sparse fields around.

A convenience function
`GenPathInfo(rootNode *castorev1pb.Node, narInfo *narinfo.NarInfo)` is
added, which is used to produce PathInfo messages, either when receiving
a NAR file over http and uploading it to a remote PathInfoService, or to
synthesize the PathInfoMessage to return to the client, if nar-bridge is
acting as a PathInfoService for a remove Nix HTTP Binary cache.

//tvix/nar-bridge

This exposes a HTTP Binary cache interface (GET/HEAD/PUT requests) for a tvix- store.

It can be used to configure a tvix-store as a substitutor for Nix, or to upload store paths from Nix via nix copy into a tvix-store.
