Finalizing hardware

I crimped and soldered almost the remaining wires, I’ve made some last redesigns to the arm CAD and I’m now fitting everything into the new prints and assembling.

I’ve also had a ton of trouble with my servo PCBs lately, but I found out a lot of the issue was my programmer is actually fried somehow, so I’m now using an old RPi Pico to act as a UPDI adapter so PlatformIO can now successfully program the ATtinys much better now.

A lot of the CAD was slightly tweaked so that everything fits better
