Add basemaps via cartoee

[FeiYao-Edinburgh]

Description

geemap and cartoee are excellent for producing interactive maps and publication figures, respectively. Both can visualize gee datasets. However, cartoee currently lacks the capability of adding basemaps. I wonder if you can add this capability such that we may have the option to produce publication figures with some basemaps as background. This should be at least useful for: 1) preparing a map describing the study area; 2) helping visual inspection in some cases.

Good suggestion. This feature has been implemented. See notebook example
