Changed all holes to non-plated and looked around for cheapest PCB options!

I just realized that my mounting holes for the OLED were plated for some reason which was totally unnecessary.

Additionally, I looked at JLCPCB, PCBWAY, and OSHPARK, and found that OSHPARK had the cheapest PCB (although it will take like 2-3 weeks to arrive, hope the PCB doesn’t have issues because I won’t have time to iterate before the deadline).

Last thing I did was I found a entry in the BOM that was accidently left there from an earlier revision (some screw terminals) and removed them.
