About passing this pointer to notifyCallback in BLERemoteCharacteristic

Currently, notifyCallback is a plain function pointer and there is no direct way to pass the this pointer to the callback function. It is better to change to C++ std::function.

Does notifyCallback work correctly?

@anhvu100 ... is your question similar to this discussion?

#311

If yes, maybe we can consolidate our discussions there?

[anhvu100]

Right. It is the same with that discussion.
