Simplify nationalMode option. Previously, when nationalMode was set to false, the plugin was needlessly creating a worse UX for users who typed a valid national number in 2 situations: (1) it wouldn't update the flag between NANP countries if you typed a different area code (in national format), and (2) isValidNumber would return false for a valid national number.
