Support for comma delimiter

Awesome library. Could definitely put this to use. Do you plan to add support for comma delimiters for thousand, millions, etc.? (e.g 1,000.00 or 1,000,000.00)

That's a really good idea, I wish I realized it during development. As of now I have no plans to update the project unless there is some iOS update that breaks the project. If I end up updating ScrollCounter to support a new iOS, then I'll look into comma delimiters. In the meantime, I'm happy to review a PR if you want to give it a shot :)

Thanks for checking out the ScrollCounter!
