LibUnicode: Begin parsing and generating locale number systems

Browse source 
The number system data in the CLDR contains information on how to format
numbers in a locale-dependent manner. Start parsing this data, beginning
with numeric symbol strings. For example the symbol NaN maps to "NaN" in
the en-US locale, and "非數值" in the zh-Hant locale.
