New-RegEx: -NotCharacterClass, -NotLiteralCharacter

[StartAutomating]

Is your feature request related to a problem? Please describe.

Regex character class subtraction is annoying.

New-Regex should include something to abstract it.

Describe the solution you'd like

New-Regex should add -NotCharacterClass and -NotLiteralCharacter.

Without additional parameters, these should act like -CharacterClass and -LiteralCharacter, except that the selection set should be prefixed with ^ (to indicate that it is not those characters)

When provided with -CharacterClass or -LiteralCharacter, these should create a character class subtraction.
