Make several data external instead of bundled:

Also dist/data/* contains minified files now

These are now external and will fetch as needed:
-export { dataAddressFormats } from './address-formats.json';
-export { dataDeprecated } from './deprecated.json';
-export { dataDiscarded } from './discarded.json';
-export { dataLanguages } from './languages.json';
-export { dataPhoneFormats } from './phone-formats.json';
-export { dataShortcuts } from './shortcuts.json';
-export { dataTerritoryLanguages } from './territory-languages.json';
