Edward Welbourne 424d9e9e56 Add byte-based units to CLDR data 
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().

"""Convert CLDR data to qLocaleXML
The CLDR data can be downloaded from CLDR_, which has a sub-directory
for each version; you need the ``core.zip`` file for your version of
choice (typically the latest). This script has had updates to cope up
to v29; for later versions, we may need adaptations. Unpack the
downloaded ``core.zip`` and check it has a common/main/ sub-directory:
pass the path of that sub-directory to this script as its single
command-line argument. Save its standard output (but not error) to a
file for later processing by ``./qlocalexml2cpp.py``
