Add temperature_array processing, update validation, add temperature range validation, remove parsing for EDTA, update models, return tuple of alloy and temperature array with create_alloy_from_yaml

Update SS316L.py to use the energy_density_total_enthalpy model and the new implementation of prepare_interpolation_arrays

Add bounds check to prevent out-of-bounds access. Ensure idx_E_neq can't exceed size-2 for safe interpolation.
