Fixes #10.
@dastels Could you test this? The sending now appears to be correct: it will send no more than 20 bytes at a time.
A BLE notification is sent after each write. If the receiver does not handle the writes fast enough, bytes will be dropped. I tested by sending 200 bytes to the Bluefruit LE Connect app, and it received all 200. But a slower receiver may need to implement some kind of flow control.
