Feature request: Add a getWilayaByPhoneCode method

[Fcmam5]

As a user, I would like to have a method which it returns a wilaya code for a given phone code.
Example:

• getWilayaByPhoneCode(41) return WilayaObject{ name: 'Oran'.. }

It would be great if the method accepts full phone numbers, truncate the phone code and then return the wilaya, example:

• getWilayaByPhoneCode('0412345678')
