Bitcoin Timestamp Verify

Verify an OpenTimestamps proof (.ots as base64, from btc-timestamp or any ots client): upgrades pending proofs from the calendars, checks each Bitcoin attestation against the real block's merkle root and returns status (confirmed, pending), block height and time, the upgraded proof, and whether your text, hash or URL matches.
