PCF8574 final revision assembly speedup

What this episode covers

just before sending off our PCF8574 gpio expander breakout board, we noticed that the package we were using (QFN) was no longer available...but we COULD get the TDFN version. so a lil swapperoo and reroute occurred right before ordering the panels. super risky because we didn't test the footprint but we were pretty confident. anyways, we did want to test before our big initial fabrication run so this is us snapping off a board and hand-pasting. turned out great and we'll be making this breakout next week!
