Add translate and scale function

[AlphaRLee]

Contact @lawruble13 (Liam Wrubleski) if you need help/guidance

Expose the the translate() and the scale() functions from the ipycanvas library so that students can use it like regular functions. See Issue #86 for the rotate() function.
ipycanvas docs for functions found here: https://ipycanvas.readthedocs.io/en/latest/transformations.html

Remember to create a Pull Request to merge your code from your branch into the dev branch and notify the Library team on Slack
