just FYI these are upgraded by go mod tidy (it upgrades protobuf, go-cid, go-blockformat)

I don't quite think this one is complete, I get these errors when updating to this commit:

@whyrusleeping your PR will live in another castle. This is for the v0 filestore, you will be using the v1 filestore. There will be a duplicate of this PR against the v1 filestore.

Reminder: the v0/v1 filestore business is basically due to go-ipfs not having completed ipfs/kubo#6815 yet (it's the only item scheduled for the v0.12.0 release).

This means repos such as: go-ipfs-blockstore, go-ipfs-ds-help and go-filestore currently have multiple versions (v0 used by go-ipfs, v1 used by hopefully anyone who hasn't been weighed down by needing to migrate their data).
