Subject: [PATCH] Relax dimension requirements for some data items

Data items _atom_site_fourier_wave_vector.q_coeff_seq_id and
_atom_site_fourier_wave_vector.q_coeff may have several values
in the same data block that are lists of differing lengths as
showcased by the category usage examples in the dictionary.
Therefore, these items should be marked as having an unknown
number of elements instead of requiring them to have the same
number of elements as the modulation dimension.
