Program RGB Leds for debugging

[andygrillo]

This is a discussion for what the LEDs could indicate on the sensor board, to help users understand the status of the device.

Connection indicators

• [ ] breathing DIM CYAN: searching for WiFi
• [ ] static DIMCYAN: connected to WiFi
• [ ] breathing DIM PURPLE: can't connect to Wifi
• [ ] blinking DIM BLUE: everytime a msg is sent to cloud (1s)

Alarm indicators (fast blinking) - colors to be based on [modified Mercalli scale] (https://www.usgs.gov/media/images/modified-mercalli-intensity-mmi-scale-assigns-intensities)

• [ ] blinking BRIGHT RED: strong shaking expected here
• [ ] blinking BRIGHT ORANGE: medium shaking expected here
• [ ] blinking BRIGHT GREEN: weak shaking expected here

Other indicators

• [ ] 3 blinks YELLOW: (during setup loop by confirming with accelerometer values) - device is properly installed horizontally on vertical surface

In this initial Blink NeoPixel LED Status stages commit from several weeks ago, I emulated the Particle Photon color indicators from https://docs.particle.io/tutorials/device-os/led/photon/

I like your LED color proposals.
