Add Nicla Sense ME dashboard

[marqdevx]

In this PR I've:

• Added inclusion of the Nicla Sense ME board (sketch)
  • Change UUID
  • Add new sensors
  • Add callback on disconnection so the LED will turn red automatically.
• Changed the style of the "new" dashboard
  • Add Arduino PRO logo
  • Change widget sizes, now there will be no weird spacings
  • Add snackbar with info at the top, user can remove the snackbar notification
  • Change the Pair button with the "PRO colors"
  • The board as it is smaller, the 3d preview camera is closer to the 3d model
  • Rotation of the 3D board is done with quaternions from the device
• Inside the Readme added the "new" dashboard, and linked a small tutorial explaining how to use Nicla's dashboard

Just a few things left to do. Please have a look at the comments.

• For me the LED color on the board doesn't match the color on the board.
• The LED color is not in sync when the app is loaded
• The LED light source comes from a weird place, should be the thing next to the reset button (see image)
• I suggest to add a background color to the 3D canvas. E.g. #58585A otherwise it's really hard to see.

• For the LED sync: Please check if you have the latest BHY2 library version, they changed the gbr to rgb.
• When the sketch is loaded the board is green, then if you change the Color selector it will apply the selected color to the board
• I will try to fix the light origin
• I'll try that color for the background

Everything added/fixed

New stuff:

• Now the dashboard will appear with the LED on green.
• On connect, the LED will be blue (both color picker and the device)
• When the device gets disconnected, the LED will turn red (both web dashboard and the board)
• Camera is closer to the board (as it is smaller than the Nano BLE Sense)

I'd rename the button. "Nicla" is the name of a whole product family so I'd try to avoid using it.
