Getting an error when trying to run an inversion with the example ini file. The `get_data` function can't seem to find obs data (TAC, ch4) which is preventing the `combined_scenario` from being created. The error message is:
UnboundLocalError: local variable 'scenario_combined' referenced before assignment
UnboundLocalError: local variable 'scenario_combined' referenced before assignment
