Completely reset TCC services database in macOS

Note: Both the system and individual users have TCC databases; run the script as both
      a user and as root to completely reset TCC decisions at all levels.

2018-08-15: Resetting the 'Location' service fails; unknown cause
2018-08-16: Confirmed the 'All' service does not really reset _all_
            services, so individual calls to each service is necessary.
2019-06-04: Still working in 10.15 beta :)
2019-08-16: Added new Catalina services (thanks @frogor)
2020-11-27: Corrected line `SystemPolicyDownloadsFolder` (thanks @tie)

The cause that reseting 'location' fails is because Location Service itens are not managed via TCC database.

All those location items listed under Privacy -> Location Services are managed by the locationd daemon.

They are all configured inside a plist file located at: /var/db/locationd/clients.plist

Line 51, SysyemPolicyDownloadsFolder should be SystemPolicyDownloadsFolder.

The print commands needs to be updated

        print ("Reset"), service
        print ("Unable to reset"), service

or they error

"Syntax errors detected :

Line 67:
