BLE5 features to use with C3/S3 (#5085)
Added new BLE5 features to use on C3/S3 family: extended scan, extended/multi advertising New code is not fancy (no feedback from events), but i think it is functional. To get feedback from events i am suggesting to use custom GAP callback, which is already implemented in BLEDevice.

/*
2+
BLE5 extended scan example for esp32 C3 and S3
3+
with this code it is simple to scan legacy (BLE4) compatible advertising,
4+
and BLE5 extended advertising. New coded added in BLEScan is not changing old behavior,
5+
which can be used with old esp32, but is adding functionality to use on C3/S3.
6+
With this new API advertised device wont be stored in API, it is now user responsibility
