Spatial Modifier (#1196)

* - Spatial Modifier Method
- Fix bug for thermal modifier. It material property was not defined in AEDT file, thermal modifier was not applied.
- Fix bug with Auto TML
- Add option to have thermal and spatial modifier in the same property

* - Improve coverage

* - Improve coverage

* - Improve coverage

* - Bug in Unittest
