`add_fax_file`Use this when the person’s file is on their own disk, where you can run commands. Puts a PDF from the person’s own disk on their XipFax draft. A photo of any kind, such as a JPEG, PNG, HEIC, WebP, GIF or AVIF, goes as a PDF made from it first on their computer, upright as a photo viewer shows it: on a Mac, `sips -Z 2100 -s format pdf <photo> --out <name>.pdf` makes one, upright and at most 2,100 pixels on its long side. Any other kind of file, such as a Word file, goes once saved as a PDF. Work out the PDF’s size in bytes and its SHA-256 first, with a command such as `shasum -a 256 <file>`, and give both. The answer is an address good for 15 minutes and the headers to send with the file: PUT the file’s exact bytes there with each of those headers, such as with `curl --upload-file <file> -H "<name>: <value>" "<address>"`, then call finish_fax_file. The address takes this file alone. PDFs only, 40 MB at most.	Use this when the person’s file is on their own disk, where you can run commands.

`add_fax_file_from_url`Use this when the person’s PDF is at a public link.

For a file on the person’s own disk, use add_fax_file. Give send_fax its id.	Use this when the person’s PDF is at a public link.
