Support multi-line text rolling in a rect about asciimatics

[peterbrittain]

Thanks for getting in touch. Can you explain your thinking a lttile more?

In particular, how are you trying to use this function and have you tried any of the options already available in asciimatics:

• Textbox with wrapped text
• The underlying code used for the wrapping (widgets.utilities._enforce_width)

I think that they cover your existing rollText implementation...

Thank you for paying attention!

With the help of your reference, I see that widgets.utilities._split_text() perfectly implements my request. Good work, and thanks greatly for making this library available!
