Description

 
When parsing a Brazilian phone number without the + prefix, the Phonelib.parse method does not correctly identify the country. However, adding the + prefix works as expected.

require 'phonelib'

Phonelib.parse('554197520226').country

=> nil

Phonelib.parse('+554197520226').country

=> "BR"

Expected Behavior

The method should correctly identify the country as Brazil ("BR") regardless of whether the number is prefixed with +.

Actual Behavior

The method returns nil when the + prefix is omitted.
