When I plot multiple lines using xarray.plot.line(), I would like xarray to be able to get the colors from a dictionary and use that for the color of the lines.

### Describe the solution you'd like

There are 2 functionalities that can solve this problem
1. Add an argument that takes a dictionary and used the colors provided in the dictionary if the corresponding labels exist.
2. Make it possible to add a colormap dictionary to attributes and xarray.plot uses it whenever a color corresponding to the dimension exists.
