Sense Hat to work on Pi 3 B running Ubuntu Mate 18.04.3 LTS

A quick search found this page:

https://sense-emu.readthedocs.io/en/v1.0/install.html

where it states: Ubuntu
To install from the author’s [PPA]: https://launchpad.net/%7Ewaveform/+archive/ppa

$ sudo add-apt-repository ppa://waveform/ppa
$ sudo apt-get update
$ sudo apt-get install python-sense-emu python3-sense-emu sense-emu-tools

I have no idea if this will work or not. Good luck Andrew and everyone else.
