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.

c4ee942b1c feat(tvix/store/protos): rename Get to Read, add Stat method
Stat exposes metadata about a given blob,
such as more granular chunking, baos.
It implicitly allows checking for existence too, as asking this for a
non-existing Blob will return a Status::not_found grpc error.

The previous version returned a Status::not_found error on the Get
request too, but there was no chance to prevent the server from starting
to stream (except sending an immediate cancellation).

Being able to check whether something exists in a BlobStore helps to
prevent from uploading in first place.

The granular chunking bits are an optional optimization - if the
BlobStore implements no more granular chunking, the Stat response can
simply contain a single chunk.

Read returns a stream of BlobChunk, which is just a stream of bytes -
not necessarily using the chunking that's returned in the reply of a
Stat() call. It can be used to read blobs or chunks.

1c15154b83 feat(tvix/store): make blobstore stream chunks
This changes the RPC methods to return/consume a stream of chunks, instead of a
very big message containing the whole blob, to keep message sizes in manageable
sizes (less than 4MiB).

a91e6334ff feat(txix/store/protos): init go.mod, generate .pb.go files
This allows importing the generated .pb.go files into other go projects.

I initially looked at buildGo.protos, but it doesn't work for multi-.proto
files, and actually having LSP support for the generated structs is nice, too.
