Scan CLDR for {,kilo,mega,giga,tera,peta,exa}byte forms and their IEC
equivalents, providing SI and IEC defaults when missing (which all of
IEC are) in addition to the usual numeric data. Extrapolate from any
present data (e.g. French's ko, Mo, Go, To imply Po, Eo and, for IEC,
Kio, Mio, etc.), since CLDR only goes up to tera. Propagate this data
to QLocale's database ready for use by QLocale::formattedDataSize().
