Reducing H_1 (#45)

[hprshayan]

Hi. I gave it a try in response to #45. Specifically, instead of propagating all items of each itemset to the _ap_genrules function, I only include the items that have confidence > min_confidence in H_1.

Great! Thank you so much.

The linting is a bit strict, could you run black like in the Gh action?

black . -l 120;

[hprshayan]

Done. Black does not compromise!

Merged. Thank you so much for this Shayan!
