Feature request: Title Case

**Is your feature request related to a problem? Please describe.**
CyberChef supports Uppercase, Camelcase, etc., but doesn't support title-case

**Describe the solution you'd like**
A new conversion that follows the NY Times style and cleverness of https://github.com/ppannuto/python-titlecase

**Describe alternatives you've considered**
I go to https://titlecaseconverter.com/ or run a JS script to interface with their API

Review CyberChef's existing Uppercase and Camelcase conversions, then compare the requested behavior with the linked python-titlecase project and NY Times style. Done means CyberChef offers a title-case conversion whose output follows that style; the issue does not name a file or test to run.
