[Enhancement] Read events for GATT characteristics

[Kyemate]

I'm building a BLE door controller and need to generate a new nonce every time someone reads from my characteristic. Right now I can only handle writes with WriteValueEvent, but reads just return whatever value is stored.

What I need:
Generate a fresh nonce each time a client reads from my characteristic (for security reasons).

Possible solutions:

• Make ReadValueAsync virtual
• Add a ReadValueEvent like we have for writes
• Some other callback for reads

This is for a door access system where each client needs a unique challenge to prevent replay attacks.

Any ideas how to make this work with the current library?
