Simplified wi-fi, reverting back to explicit AP or STA modes.
Moved wifi ssid and password to Secrets.h file, which is intentionally omitted from git.
Commented out websockets while troubleshooting wi-fi and jitter issues.
Removed delay while wi-fi connecting, just show the LEDs already!
WIP jitter fixes/improvements.  This configuration all but eliminates jitter on my test setups.
Added different FastLED interrupt options (commented out).
Auto-formatted file.
