Added support for LocaleId's, Added access members for fields and Significant refactoring

• Include support for LocaleId's and printing of all fields (currency, script, variants, subdivisions)
• Add support for currency and subdivisions CLDR data
• Improved compile times, resulting file size etc. by changing maps from CanonicalizedMap to
  const {}, etc.
• NOTE: Lookups via the operator [] are still case-insensitive, however direct access to
  the languages.languages, territories.territories etc. members become case sensitive.
• Added non-countries to territories map
• Added static access members for languages, territories, scripts, variants and currencies.
