Add Box shape to ansys.geometry.core.shapes subpackage

Maybe all of this is contained client side but would be nice to move server side in either this first implementation or future refactors.

Accept in the required inputs to create a box in a method on the Component class. The call to the server should return a Body that will be nested under the Component in context.

Example client script is within BoardCreationCommonHelper for reference.

#105 simply adds convenience for sketching, would still also need an "Add 3D Box" method as well. Tagged sketch implementation as another route for the user while waiting on gRPC endpoing for adding the 3D Box

@chadqueen your "Add 3D box" already exists - see #21

FYI - building a box should be always client side. This shape/body ay be of use to any potential end-user without needing to build a server connection
