Subject: LibUnicode: Generate primary and secondary number grouping sizes

Most locales have a single grouping size (the number of integer digits
to be written before inserting a grouping separator). However some have
a primary and secondary size. We parse the primary size as the size used
for the least significant integer digits, and the secondary size for the
most significant.
