Support for matrix operations

[RSKothari]

Hello,

Is there a plan to extend this awesome work to support matrix operations? For example, converting XYZ matrices to sRGB matrices.

The API does ship with already a few pre-computed, e.g. https://github.com/gtaylor/python-colormath/blob/master/colormath/color_objects.py#L715. Is there a use case where you would need to do the computations yourself?
