Fixed connection update not working in obfuscated applications (#634)

Proguard by default removes unused code. BluetoothGattCallback.onConnectionUpdated() function is hidden in AOSP and therefore Proguard removes the callback. Added a correct consumer Proguard configuration to the library package so the callback will not be renamed/removed.
