Title: Request add Buddhist Era

update formatLocalized() function to support Buddhist Era. This add boolean to check when require Buddhist Era format.

It's not a gorgeous way to solve Year/Calendar format.

imo: future version should use IntlDateFormatter(). It's quite new, but it is a gorgeous way than this way.
