Fix LT3755 ISN/ISP current-sense pin ordering

KiCad Bot requested to merge github/fork/MatthewStephenson/LT3755-PinOrderFix into master

Created by: MatthewStephenson

This change fixes the vertical order of the ISP and ISN current-sense pins so that the positive current-sense pin is uppermost on the diagram. This error caused me to have PCBs manufactured with these pins incorrectly wired, because I didn't think to check that the positive sense pin was at the top.

Before this change it was necessary to cross the current-sense wires as shown, because the ISN (negative) pin was uppermost:

After this change the wires don't need to be crossed:

This change is consistent with the diagrams in the datasheet which have ISP uppermost:
