Fix manualfocusdrive based focus bug due to fix in commit de12d97ddefc
Summary:
Manualfocusdrive command needs to get negative numbers for inward direction.
Next step is to replace conditional logic with e.g. strategy pattern
Test Plan:
Regression tests on the simulator and Canon 40D for relative focus position
Test on Nikon Z6, Nikon D 7100, Canon 40D for manualfocusdrive with iterative and polynominal algorithms.
