Bgm racp

[cjf12harry]

This pull request implements the RACP characteristic for the Glucose Profile. RACP is the record access control point, which the client will interact to query records.

The mapping of this characteristic can be found in https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.characteristic.record_access_control_point.xml . We use it as a guide to do the serialization and deserialization.

The constructor for this characteristic take in a BluetoothGattCharacteristic object from the Android Bluetooth stack, parse and create a RACP object. This RACP object has all the deserialized data field available for the business application.

Different from other characteristics, the RACP not only does the reading (hence need parsing) from a remote device. It also do the writing to a remote device. As a result, we need to do serialization (composing). We implement a Composable interface, so that we can converted a RACP object into byte array that can be consumed by the Android Bluetooth.
