Design ready/choropleth

[Arbyhisenaj]

Description

Built the Choropleth legend

It has a lot of shared logic with the map layers so it's consistent (e.g using interpolateBlues)

The loading state could be improved. Having a spinner was glitching the layout so i had to keep it blank. Also, I'm not sure if it's location in the code is the best but overall, it's ready enough to demo.
