Use ansys.tools.common for example data download

[greschd]

• Use ansys.tools.common.example_download for downloading data from the ansys/example-data repository instead of directly downloading with urllib.
• The download is still wrapped in our own function to keep the enum-based interface for the example data.

The switch between github and a local file URL was handy to implement new examples and for testing purposes. Is that still easy possible?

[greschd]

Good point. It's not possible as-is AFAICT, but we can implement it either here or within ansys-tools-common.

[roosre]

The same is used in PyDPF-Composites and I assume other would benefit as well. Do you mind to implement it in the ansys tool?
