Clients should publish a `2001` kind event after chunking the file in order to store the list of chunks
The events `content` MUST be a new-line delimitated list of sha256 hashes
The events MUST contain an ordered list of `chunk` tags with the sha256 hashes of the chunks

### Metadata
The `2001` event MAY include additional metadata tags to help other clients know the filename, mime type or servers to download from
Metadata tags:
- `name` Filename
- `summary` A short summary of the file
- `mime` Mime type of file
- `size` Total size in bytes of the file
- `server` (multiple) Recommended servers to download chunks from
