Adafruit-circuitpython-matrixportal

This release includes the following changes
* HTML Color code converter so it can seamlessly deal with Adafruit IO colors like `"FF0000"`.
* Fixed an issue if init with a json transform
* Exposed graphics and network so I didn't have to add functions in 2 places
* Added set_text_color so labels can have the color value changed
* Moved some common code for setting the scroll index when scrolling text added
