Introduce Golang examples

[vijaiaeroastro]

This PR introduces 7 golang examples (same as Python examples)

• 3mf_convert.go
• add_triangle.go
• beam_lattice.go
• color_cube.go
• create_components.go
• create_cube.go
• extract_info.go

It currently imports the lib3mf library from https://github.com/3MFConsortium/lib3mf.go
Once ACT is patched / a decision is made on patching the bindings in the repo, examples can be adapted to work with local binding files

This PR also tests the create_cube.go script in Windows, Linux and OSX as a part of the deploy stage.

The only solution that worked was bumping the Golang binding version to 2.4.1. It seems that the Golang package server caches the version, making it immutable.
