no support for UART text packets

[TonyLHansen]

The Bluefruit LE Connect application is capable of sending text data over BLE, using the UART module and entering a string. The data is sent as is, followed by a newline.

The arduino sample code for LED Glasses supports this, but there is no corresponding CircuitPython support in the adafruit_bluefruit_connect library.

Pull request #33 provides a patch for this.

The new packet type is called RawTextPacket, found in Adafruit_CircuitPython_BluefruitConnect/adafruit_bluefruit_connect/raw_text_packet.py
