Investigate BLE scanning not working on MacOS 12

[sureshjoshi]

Everything works fine on iPad, iOS, and Catalyst - but Swift command line apps on Mac OS 12 are no longer scanning.

Still need to test on a device that advertises

[sureshjoshi]

Confirmed that I can scan for and discover BLE devices if they have an advertised service that I can find via:

centralManager.scanForPeripherals(withServices: [CBUUID(string: "180A")], options: [CBCentralManagerScanOptionAllowDuplicatesKey: true])

In this case, I exposed 180A (Device information service) just for the sake of something simple.

I didn't appear to run into any problems here anymore. Added a Central example, and it can detect seemingly everything around me.
