Partition charts don't accept theming via color array

[wylieconlon]

This is a request for partition charts to take a color input such as color={['red', 'green', 'blue']}, and to use the defined colors as a theme. Each color in the theme would be used sequentially for the first layer, cycling if there are more sections than colors.

The result would look like the sunburst examples:

This is possible today, but the proposed API simplifies the most common usage.
