fp-finder: tool to find potential false positives in data files

[fzipi]

Requirements

We had an utility, fp-finder, that uses wordnet to find english words that could be potential false positives in data files. Original code can be found here: https://github.com/coreruleset/coreruleset/blob/v4.7.0/util/fp-finder/spell.sh

1. Replicate the same functionality, maybe using https://github.com/fluhus/gostuff/tree/master/nlp/wordnet
2. Need to find out if we should include one dictionary, or it can be downloaded in the fly using hashicorp/go-getter
