Fetch IPFS and FIlecoin information on nodes that have pinned a CID

[jsolly]

IPFS

• Nodes pinned

FIlecoin

• Number of deals
• Number of unsealed copies

Optional Possibilities (for future PRs)

• Information about deal expiration
• Unique Peer IDs storing data
• Where it is stored (geo location)
• Protocols available for unsealed copy (Graphsync, Libp2p, HTTP)?

Would be useful to know the number of peers (nodes) storing the CID, I believe you would use this command

ipfs dht findprovs <CID>

https://docs.ipfs.tech/reference/kubo/cli/#ipfs-dht-findprovs

We want this info to be served via our API. So take this information and what we get from CID.contact to know both IPFS and Filecoin metadata.
