Add phone number parsing functionality

Added a new method 'parse' in the PhonenumberHelper class in ChillMainBundle to sanitize and parse phone numbers. This method specifically handles phone numbers that start with '00', '+' or '0'. Associated unit tests for this new method were also added in PhonenumberHelperTest.php.
