Cloudflare Stream now supports NFTs

Introduced an API to associate ERC-721 token IDs and contract addresses with Cloudflare Stream videos, enabling NFT-based ownership representation. Added a claim API that allows the owner of an NFT to take administrative control (including deletion) of the associated video on Cloudflare Stream by proving ownership via a signed message. The Stream video player will now display a link to the associated NFT contract and token.
