feat: allow for multi_colors argument in plotting options

[RobPasMue]

Closes #117

This will allow to do the following (from PyAnsys Geometry, for example):

from ansys.geometry.core import launch_modeler
from ansys.geometry.core.math import Point2D
from ansys.geometry.core.misc import UNITS
from ansys.geometry.core.sketch import Sketch

modeler = launch_modeler(mode="docker")

design = modeler.create_design("my_design")

# Create a sketch of a box
sketch_box = Sketch().box(Point2D([0, 0], unit=UNITS.m), width=30 * UNITS.m, height=40 * UNITS.m)

# Create a sketch of a circle (overlapping the box slightly)
sketch_circle = Sketch().circle(Point2D([20, 0], unit=UNITS.m), radius=3 * UNITS.m)

# Extrude both sketches to get a prism and a cylinder
prism = design.extrude_sketch("Prism", sketch_box, 50 * UNITS.m)
cylin = design.extrude_sketch("Cylinder", sketch_circle, 50 * UNITS.m)

# Design plotting
design.plot(multi_colors=True)

# Close the modeler
modeler.close()

This will require a new release

LGTM, thanks for this implementation 🙂

I can release once this is merged.
