REVISION SUMMARY
  Improve Focus Module in Ekos by adding autofocus support for DSLR's that use manualfocusdrive command by gphoto instead of rel_focus_position for example, Nikon Z6 <https://phabricator.kde.org/Z6> according to the documentation http://www.gphoto.org/doc/remote/.
  Nikon DSLR: Manual focusing only works in the "liveview" aka "preview" mode (with mirror up). In "non preview" mode the focus motor is only controllable by the autofocus engine. --set-config manualfocusdrive=step size

TEST PLAN
  1. Regression tests on the simulator for relative focus position
  2. Test on Nikon Z6 <https://phabricator.kde.org/Z6> and Nikon D7100 <https://phabricator.kde.org/D7100> for manualfocusdrive with iterative and polynominal algorithms.
