Before, BitBox::from() internally created a U2fCommunication framing layer. We remove this and fold it into the ReadWrite trait that BitBox::from already takes. This way, the connection code can choose the framing. This will allow making a BitBoxBridge communication layer, which uses a modified u2f framing protocol.
