An automated utility to upload daily crosswords to your Supernote Cloud

Currently, the script (running every 6 hours by GitHub Actions) will deliver the following puzzles:

• The Guardian
  • [Mon-Sat] Quick crossword
  • [Mon-Sat] Cryptic crossword
• Wall Street Journal
  • [Mon-Sat] Standard crossword¹
  • [Sat] Variety crossword
  • [Sat] Number puzzles

1. On your Supernote, create a folder under Document called Crosswords, and sync with Supernote Cloud
2. Fork this repository to get your own copy
3. In your fork's settings, go to Security > Secrets and variables > Actions add two Repository secrets to hold your Supernote Cloud login credentials:
   • SUPERNOTE_CLOUD_EMAIL
   • SUPERNOTE_CLOUD_PASSWORD
4. Wait for the script to run on schedule, or manually trigger it on the Actions tab
5. On your Supernote, perform a sync with Supernote Cloud, and check your Document/Crosswords folder.

Puzzles are named with the following format (making them nicely sortable):

{yyyy}-{mm}-{dd}-{provider}-{kind}.pdf

I wrote a library that can communicate with Cloud, based on inspection of how the web UI communicates with the Supernote back-end and AWS S3 (where uploaded documents are actually stored).

If it's a useful enough library, I may extend it for other usage (downloads, folder creation, etc.), but for now it only implements the API calls needed to facilitate authentication, directory traversal/listing and uploads.
