[Feature request] Add labels to phone & email objects

[tarasmelnychuk]

Would be great if email & phone objects will contain labels.

Here is how I imagine ContactInformation type after update

interface ContactConnectionProperty {
  value: string;
  label: string;
}

interface ContactInformation {
  emails: ContactConnectionProperty[];
  firstName: string;
  lastName: string;
  numbers: ContactConnectionProperty[];
}

https://stackoverflow.com/a/10275572 - described how to retrieve labels from kABPhoneProperty and kABEmailProperty. Unfortunately, can't create PR for it since I'm familiar with C languages
