Suggestion: cubit for geometry preparation

[lukethehuman]

Implement a parametric geometry preparation step via coreform cubit. Maintain the option to forgo this option and prepare geometry directly with MOOSE.

Coreform cubit is often used for meshing parametric geometry, particularly for more challenging or complex geometries. It would be useful to support this option in SLEDO. However, as cubit is a licensed software, the option to prepare geometries directly in MOOSE should remain the default option.

Currently working on this with a closed source cubit-based geometry engine. The desired outcome of the work is that this tool will be open sourced and the resulting interface with sledo added in a future update, which would resolve this issue.
