Add macro zone grouping (6 groups) as map default

Nine fine IW zones over-fragment low-dimensional maps: English-speaking + the
European religions (Protestant/Catholic/Baltic) don't separate, and 'Confucian'
reads oddly for Japan. IW_MACRO collapses to 6 principled groups (West, Orthodox,
East Asia, Latin America, African-Islamic, South Asia); zones_for(macro=True) is
the default, macro=False keeps the principled 9. mfq2/big5 read much cleaner; 16pf
still overlaps (that instrument doesn't separate cultures).
