The co-analysis of 2 polarized maps at different frequencies produces 9 different spectra,
yet write_cl can only write 6-column tables.
Making the routine more flexible in that respect would be quite relevant.
It would also be nice to have an extra_header keyword in that routine, just like in write_map, so that the origin of the C(l)
can be documented in the FITS header.
