Feature request: Add `getPhoneCodeForWilaya` and `getPhoneCodesForWilaya `

[Fcmam5]

⚠️⚠️⚠️
This issue is for first-timers only, we'd like you to start your open-source journey from here 😄 ⚠️⚠️⚠️

As a library consumer, I would like to have a method that returns phone codes for each wilaya.
One of the use cases for this feature is with forms; in order to have a better user experience, we would like to set the phone code initials when the user select their wilaya. For example: if I fill the address block and set my city to Oran (code: 31) I would like if the phone number block is set automatically to 041.

What we want to add:

• A getPhoneCodeForWilaya function that takes one parameter (wilayaCode: number) and returns the first phone code (as a wilaya, like Algiers have two phone codes: 21, 23).
• A getPhoneCodesForWilaya function that takes one parameter (wilayaCode: number) and returns an array of all phoneCodes of that wilaya.

NB:

• Please read our contributing guidelines and our code of conduct
• Comment here so we know that you're on it 🐝 .
• Clone this repository, read the code and try to understand how we structured it.
• Start hacking (PS: You can check the PRs we merged and see how our smart contributors added this kind of features)
• Update documentation in the readme file
• Ask for help, here or in Slack.

Happy Hacking !
