[Request] Make it possible to use SteamDB Free Packages link

[twistedmywords]

Describe the request

Make it so you can use SteamDB's Free Packages link as an importer for game IDs.

https://steamdb.info/freepackages/

Expected behavior

In this scenario, ideally the script would pull IDs from that page and redeem them.

If the ID was already redeemed to the account, you could skip those which would further help reduce rate limiting.

If possible, making it work with their filtering on the Free Packages page so you could remove the demos if you wanted.
