add RemoteCamera sample

[omichde]

Testing out MultipeerKit and its broadcasting feature, I've added a classical Photo Sharing sample. It shows you how to:

• call the photo picker
• encode an UIImage as Codable (via custom encoder)
• embed MultipeerKit in a classical view controller setup
• shares a photo between all peers (broadcast)

Have fun...
