feature request - filter prime gaming key type

[frostworx]

Hi,

Thank you very much for your work on this tool!

I recently tried it_(via home assistant addon)_ and it worked fine ootb.

I do not really care about Amazon internal games and would like to ask if it would be possible to add a key type filter for prime gaming, so only cherry picked game keys (e.g. gog, steam, epic games) are auto claimed and all not selected are auto-skipped.
