Added some missing frameworks to the DDC.h which Xcode 13.0 complained about.
Avoid the 'duplicate symbol' linking error (for _DDCDelayBase) which Xcode 13.0 complained about.
Changes to the example script :
- Added a state file to the example script; maintaining brightness, contrast and volume settings for monitor firmwares lacking support for relative adjustments.
- Added a poweroff option

Xcode 13 is still beta so can't validate the fixes herein - will wait on merge until I can validate
