Side-entry JST connectors have reversed pin numbering vs datasheet #159

Description

@Arctic-git

All JST side-entry connectors in this library that i've checked have reversed pin numbering compared to the official JST datasheets, while top-entry connectors are correct.

This results in top-entry and side-entry variants of the same connector having different wiring orders, making them electrically incompatible even though they should be.

For several JST series (e.g. GH), the pin numbering on the footprint differs between top-entry and side-entry types because the plug housing is inserted differently relative to the footprint.

On this drawing you can see where pin 1 should be on the JST GH series (https://bluerobotics.com/learn/wl-connector-standard/)

But in this library top/side types have the same numbering which places pin 1 on the wrong physical side for side-entry connectors.
