### 🐞 Description of the bug

The experimental data from `ansys.additive.core.examples.download_material_tuning_input` only has one entry, which will result in an exception from the custom material tuning process. The experimental data file should have at least two entries to have a successful example.

### 📝 Steps to reproduce

Run `04_custom_material_tuning.py`.
The output from `print(summary)` will be:
`optimized_parameters_file: C:\Users\adeleon\AppData\Local\Ansys Inc\pyadditive\zggXdiM9xR1F\optimized_parameters.csv
coefficients_file: None
material_configuration_file: None
characteristic_width_file: C:\Users\adeleon\AppData\Local\Ansys Inc\pyadditive\examples\material_tuning_input\characteristic_width_lookup.csv
log_file: C:\Users\adeleon\AppData\Local\Ansys Inc\pyadditive\zggXdiM9xR1F\log.txt`

The coefficients_file and material_configuration_file being None indicates an unsuccessful tuning.
