Cutoffs are not passed properly to ALM

Describe the bug

When the phono3py is run with --alm --fc-calc-opt "cutoff=FC2_CUT|FC3_CUT" only the FC3_CUT value is passed to ALM and in consequence FC2_CUT is overwritten.

Work-around

I have found a work-around for this by passing fc2_calc_opts and fc3_calc_opts joined by space to produce_fc3 (see below). But I suspect this may be not fully correct - it just works for my case.

Here is a correction in the file (cui/load.py (L441)):

    if ph3py.fc3 is None and forces_in_dataset(ph3py.dataset):
        ph3py.produce_fc3(
            symmetrize_fc3r=symmetrize_fc,
            is_compact_fc=is_compact_fc,
            fc_calculator=fc3_calculator,
            fc_calculator_options=" ".join([fc2_calc_opts,fc3_calc_opts]), # Correction HERE
            use_symfc_projector=load_phono3py_yaml,
        )

Could you try the command option -fc-calc-opt "cutoff=FC2_CUT|cutoff=FC3_CUT"?
