Delayed Reveal Batch Metadata ERC-721

Description

The DelayedRevealBatchMetadataERC721 contract is an extension that provides functionality for delayed reveal of metadata for ERC-721 tokens. It enables the uploading of metadata for ranges of token IDs with optional encryption, allowing tokens to be revealed at a later time with a decryption key. This is useful for scenarios where the token metadata needs to be kept secret until a specified time.

Callback Functions

Function	Description
`onTokenURI`	Callback function for `ERC721Metadata.tokenURI`. Returns the metadata URI for a given tokenId. If the metadata is encrypted, it returns a placeholder URI.

Fallback Functions

Function	Description
`getAllMetadataBatches`	Returns all metadata batches for a token. Each batch contains a range of token IDs, their associated base URI, and any encrypted data.
`uploadMetadata`	Uploads metadata for a range of token IDs. Emits a `NewMetadataBatch` event and a `BatchMetadataUpdate` event. Optionally includes encrypted data and a provenance hash.
