Replacing ModelMapper with MapStruct

- Removed Model Mapper from pom files
- Replaced ModelMapper with MapStruct
- Added Tests for MapStruct
- Changed mapstruct annotations for individual variables to be null safe rather than all variables
- Excluded generated code from code coverage
- Set ModuleReferences input to required for SchemaSet so that ModuleReferences list set to empty list rather than null
