Text Position Required With Scrolling

[jammininmypjs]

Adafruit_CircuitPython_MatrixPortal/adafruit_matrixportal/matrixportal.py

Line 182 in 6646a23

text_position = (self.display.width, text_position[1])

When I try to add_text to the MatrixPortal I get the error:

      File "code.py", line 85, in <module>
      File "code.py", line 70, in init_matrixportal
      File "adafruit_matrixportal/matrixportal.py", line 182, in add_text
    TypeError: 'NoneType' object is not subscriptable

In the support forums, it was determined the above line of code is expecting that you also provide the text_position parameter when specifying scrolling

Yeah, we should probably check for this when the text is added so the user has a more friendly error.
