feature idea: make it possible to search for the tag #rat in get_keyword_rule_matches()

[ruppde]

hi Flo,

yes, I know ... but still it would be nice someday to be able to search for "rat" without getting all the matches with substrings in the description like opeRATors, exfiltRATion, geneRATed, ... so maybe a parameter like noDescription? (a fullword parameter wouldn't match on e.g. njrat)

proof that the description is searched: response = v.get_keyword_rule_matches(keyword="cyberchef")
