RK-A

There are cases of KPs which are getting removed (most prominently in Library Reference) due to recent changes. It includes a variety of KPs like "one-shot (de)compression", "lexical analysis", "optional or positional arguments", etc. We need to make appropriate changes to make sure that these KPs are not discarded as they are important.

Possible routes of investigation
1) Check generate_candidates function and make tweaks in the list of POS tags
2) Modify the current filters in generate_candidates to make sure these KPs pass through. Change the if condition: "if cand_ph⁰ == variation⁰" to "cand_ph⁰ in variation"
