observeByteStream() Subscriber not cancelled

[arajthala]

Disposing observeStringStream() doesnot cancel the subscriber from observeByteStream() causing exception when trying to close connection.

Caused by: com.github.ivbaranov.rxbluetooth.exceptions.ConnectionClosedException: Can't read stream.

Start reading string stream:
Disposable disposable = mBluetoothConnection.observeStringStream() .subscribeOn(Schedulers.computation()) .subscribe(s -> Log.e("Data", s));

Stop reading stream:
disposable.dispose()

Call
bluetooth.closeConnection()

Never cancels subscriber and throws exception
