Connector JAE (LY20): differentiate pin 1 (round rect)
The old jae generators did not create a different pad shape for pad 1. This pull request changes pad 1 to be rounded rectangle. It also changes the silk outline such that it has the correct clearance to pad 1.
The line ordering for pads also changed as i now use the pad array instead of two for loops to create the pads.
