ash 07e5cd8994 Rewrite MUX: WS2812C LEDs (NeoPixel) + 74HC165 buttons 
PixelStomp MUX uses:
- WS2812C LEDs: one data line via DAT (GPIO 9), NeoPixel protocol
- 74HC165 shift register: LD/CLK/DI for reading 8 button states

Changes:
- Use Adafruit NeoPixel library for LED control
- Proper 74HC165 parallel-load shift-in for buttons
- 8 switches + 8 LEDs (was incorrectly 10)
- Diagnostic commands: dump, ledtest, red, green, blue, read

ash 102cae9d91 Add PixelStomp MUX driver (DAT=9, LD=10, CLK=11, DI=12) 
- New PixelStompMux class with shift register read/write
- Read 10 buttons via DI (active LOW)
- Drive 10 LEDs via DAT (shift out + latch)
- LED startup animation uses MUX
- Switch polling reads from MUX shift register
- MUX instance shared between switch and LED drivers

ash c94be67384 Fix for ESP32-S3-WROOM-1: safe GPIO pins, serial flush, delays 
- Switch pins: 2-7, 15-18 (avoids USB 19/20, PSRAM 26-32, JTAG 34-37)
- LED pins: 38-42, 45-48, 21 (high GPIOs, no special functions)
- Add Serial.flush() after init messages
- Increase startup delays for reliable serial output
- Board: esp32-s3-devkitc-1-n16r8

ash bb32ec65d1 Fix USB MIDI, add GPIO for switches and LEDs 
- Remove TinyUSBDevice.begin() conflict with Arduino core
- Switch stub now reads GPIO with debounce (pins 1-10)
- LED stub now drives GPIO pins (pins 11-20) with startup animation
- All pins printed to console on init
