Add check in RGBColor constructor to account for integer colors

[seanirby]

I ran into this issue while trying to add some particular colors to my named_colors configuration. Values such as 990000 will be interpreted by MPFs YamlInterface as an integer rather than a string and will cause the following error when an RGBColor is instantiated with an integer value:

Traceback (most recent call last):
  File "/home/sean/dev/mpf/mpf/tests/test_RGBColor.py", line 34, in test_int_color
    color = RGBColor(990000)
  File "/home/sean/dev/mpf/mpf/core/rgb_color.py", line 181, in __init__
    self._color = (color[0], color[1], color[2])
TypeError: 'int' object is not subscriptable

Added a check in the constructor of RGBColor to fix this particular issue.

Ideally you quote colors. We had similar issues with octal encoding such as "011111". Guess this is still a stop gap solution for some cases. Maybe we should warn users? Or raise a nice error?

Ah OK. The doc section I was referencing wasn't quoting the colors so that threw me off: https://docs.missionpinball.org/en/0.54/config/named_colors.html

I'll update to raise an error and also update that doc section.

Thanks for taking care!

Updated to output an error message instead. Sorry for the delay @jabdoa2, forgot about this one.
