bug: Custom Dictionaries Uppercased fails to match

[CyTechNomad]

Describe the bug

We use a custom dictionary for other things I was hoping to use the same dictionary here. The issue is this dictionary is all upper case. I'm not in a position to change the dictionary used everywhere else so I'm needing this library to Lower the dictionary word as it runs

What do you see?

ran with the following input list words := []string{"FUCK", "ass", "POOP", "penis", "bitch"}
and this custom Dictionary WithCustomDictionary([]string{"FUCK", "ASS", "POOP", "PENIS", "BITCH"}, DefaultFalsePositives, DefaultFalseNegatives)
im getting the following output
Expected true, got false from word FUCK
Expected true, got false from word ass
Expected true, got false from word POOP
Expected true, got false from word penis
Expected true, got false from word bitch

What do you expect to see?

I expeted it to pass the test in all cases

List the steps that must be taken to reproduce this issue

1. use custom dictionary containing uppercase words
2. Run the test

Version

latest

Additional information

I have a functional fork that i would like to bring in where i am ToLower the dictionary words as they come through the Extract profanity function

I've just made it clear in b8dfd2b, but to keep it short, all custom dictionaries are expected to be pre-lowercased.
