Describe the bug
Windows tests have been timing out due to an initialization error in lib_irradproc.cpp

To Reproduce
Steps to reproduce the behavior:

1. Run CMPvsamv1PowerIntegration_cmod_pvsamv1, NoFinancialModelModuleAndInverterModels on Windows
2. For module_model 4 and inverter_model 0, getGroundShadeFactors has some values with e-67
3. This means that the row to row shading routine never finishes before the tests update

Expected behavior
Variables should be properly initialized and the routine should finish on all platforms

Potentially need to initialize ground clearance height as 1.0 in https://github.com/NREL/ssc/blame/724d05aefd7267c66ba8d926bebd8805201ff797/shared/lib_pv_io_manager.cpp#L1321
