`draft` `optional`

This NIP provides a simple way to save spreedsheets on Nostr. 

Event kind `35337` describes a workbook with `data` tags that contain the value of each cell as well as optional styling. 

```js
{
  "kind": 35337,
  "tags": [
    ["d", "<unique identifier>"],
    ["title", "Name of this spreadsheet"] // public title
    ["data", "<sheet name>", "<column letter>", "<row number>", "<value>"]
    ["data", "<sheet name>", "<column letter>", "<row number>", "<value>", "<style>"]
    ["style", "<TBD>"] // Need to specify all options here. 
  ],
  "content": nip44Encrypt([
    ["title", "Name of this spreadsheet"] // private title
    ["data", "<sheet name>", "<column letter>", "<row number>", "<value>"] // private data
    // ... other tags
  ]),
  // ...
}
``` 

Sheets MUST be rendered in the order of their tags.
