Unify globe and map visualization utils

[jorgepiloto]

PySTK has globe and map plotters. These can work in different environments:

• GUI environment via ansys.stk.stkengine.tkcontrols
• Jupyter environment via ansys.stk.stkengine.experiemntal.jupyterwidgets

However, this forces users to know how to use each scene visualizer with the right environment.

Therefore, the proposal here is to create a common class for globe and map visualizations. Internally, the class should identify the environment in which it is running and use the right visualization backend.
