How to use the pymars.sampling.parse_psr_inputs function in pymars

for sp in safe_species:
        assert sp in gas.species_names, f'Specified retained species {sp} not in model'
    
    ignition_conditions = input_dict.get('autoignition-conditions', {})
    assert ignition_conditions, 'autoignition-conditions need to be specified'

    psr_conditions = input_dict.get('psr-conditions', {})
    flame_conditions = input_dict.get('laminar-flame-conditions', {})
    if psr_conditions:
        raise NotImplementedError('PSR sampling not implemented yet, sorry!')
    if flame_conditions:
        raise NotImplementedError('Laminar flame sampling not implemented yet, sorry!')

    # check validity of input file
    ignition_inputs = parse_ignition_inputs(model, ignition_conditions, phase_name)
    psr_inputs = parse_psr_inputs(model, psr_conditions, phase_name)
    flame_inputs = parse_flame_inputs(model, flame_conditions, phase_name)

    return ReductionInputs(
        model=model, error=error,
