Puzzmo support

[reesericci]

I'd like to request support for scraping Puzzmo puzzles.

Yeah, this would be nice. Most of the file format parsing is already handled since the New Yorker uses the same format. Some difficulties would be:

1. Obtaining the crossword data looks more challenging. https://github.com/thisisparker/xword-dl/blob/main/src/xword_dl/downloader/puzzmodownloader.py is an example implementation we could look at.
2. I think Puzzmo does some more interesting things with the format (schrodinger squares; alternate clues) that aren't well supported in most/all of the formats the Scraper supports. So there'd be some limitations there.
