feat: use service colors in plotter (upon request)

[RobPasMue]

Description

Enabling the usage of service colors upon request. Including a new library global variable called ansys.geometry.core.USE_SERVICE_COLORS. If set to True the plotter will make use of the service-defined colors. This can make large components to be plotted very slowly since it will require interaction with the service. By default, SC green will be used, just like until now.

We are also exposing these capabilities now via the plot(...) methods. Users won't have to specifically set the global variable if they just want to check it once.

Documentation and testing has been added.

Closes #433

Hi @PipKat - would you be able to review at least the mystnb file that contains the example I've worked on? Much appreciated!!

[RobPasMue]

This PR is expected to fail certain tests (at least until the new server version is available with the "null" return for colors whenever it is not assigned.
