CLI tools for the DAGStore inverted index

[nonsense]

This PR is adding 2 CLI tools to the DAGStore inverted index:

• Lookup the pieces that a CID belongs to
• Inspecting the size of the inverted index

It is not ready for merging, because we first need to:

• merge parent PR and upgrade libp2p as per the parent PR: feat: markets: Integrate index ingest protocol and retrieve by any CID #7313
• upgrade DAGStore and its APIs to the latest version (current version still refers to CIDs and not multihashes, and Size() is missing).

TODO:

• rename inverted index to piece index so it is easier for users to understand what this is about.
