Crystal Oscillator missing from Hardware Design

[cjinn]

Summary

As noted in the Hardware Design Guidelines on page 6 for the External Clock Source, the ESP32 requires a 40 MHz crystal oscillator in order to run Wi-Fi/Bluetooth firmware. This is an oversight on the hardware design, causing any firmware for Wi-Fi/Bluetooth to fail for v0.0.3b.

Proposed Solution

In the next hardware iteration, include a crystal oscillator into the design.
