When different supercell size for fc2 is used, ph3.phonon_supercell_matrix is None. This is implicitly used as the flag to invoke this mode, i.e., different supercell sizes for fc3 and fc2.
This rule was not followed in a few places, not only in CUI logic for reading various types of inputs, but also in Yaml dumper and loader.
Probably a specific flag in boolean type should be prepared.
