load locale data for each locale from a different module

[patch]

Suggested by @aarondcohen:

[13:43] Aaron Cohen: as an added benefit, you could break CLDR::Number::Data::* up by locale
[13:43] Aaron Cohen: so epople would load less into memory if they aren't using the other locales

Although the number-related locale data is relatively small per locale, the aggregate is increasingly large with each CLDR release. Another idea is to remove any data from a locale that is the same as what would already be inherited.
