I found google's phone number library using phone number list from ITU and I found ITU have well documented Myanmar list describe in the link https://www.itu.int/oth/T0202000092/en

How about adding those rules here.

Are you going to add those rules or I'm going to create new repository :C

Yes. A rule based database would be better to add it as a dependency to this project. Thank you!
