[BREAKING] Refactor NimBLEBeacon
* General code cleanup * The internal data struct type `BeaconData` is now public and can be used by the application. * `NimBLEBeacon::setData` now takes `const NimBLEBeacon::BeaconData&` instead of `std::string`. * Added overload for `NimBLEBeacon::setData` that takes a pointer to raw `uint8_t` data and length`. * `NimBLEBeacon::getData` now returns `const NimBLEBeacon::BeaconData&` instead of `std::string`.
