Destroys an asset or resource

Uploads a single chunk of a large file as part of a chunked upload process. This enables efficient upload of large files with the ability to resume interrupted uploads. Each request uploads one chunk of the file. It is required for any files that are larger than 100 MB. This is often relevant for video files, as they tend to have larger file sizes. Minimum chunk size is 5 MB. The `file` field accepts either the chunk bytes (multipart) or an HTTP/HTTPS URL. When a URL is supplied, Cloudinary downloads it and validates the response `Content-Length` against the chunk-size contract (exact match in the uniform-size flow; within 5 MB floor and 5 GiB cap in explicit-order mode) before storing any bytes. A mismatch aborts with 400 and persists no state. The remote server must return a `Content-Length` header; chunked transfer-encoded responses are rejected. **Explicit-order totals** (`X-Upload-Part-Number`): `X-Upload-Total-Parts` may be omitted on non-terminal chunks until the session total *N* is established by any earlier chunk that sent the header. After *N* is known, the chunk for part index *N* must include `X-Upload-Total-Parts: N`. Whenever the header appears, its value must be the same integer *N* for that `X-Unique-Upload-Id` (no conflicting totals).
