@nivo/rects and @nivo/icicles package

[lsagetlethias]

Highly inspired from @nivo/sunburst, @nivo/arcs, and https://observablehq.com/@d3/zoomable-icicle.

The main goal was to add a "flat" version of the Sunburst chart.

This PR is pretty complete but some TODO remains which are not critical and I don't know how to resolve them for now:

• @nivo/rects:
  • Add transition mode like what's arcs package has builtin
  • Create a useAnimatedRect hook for single rect animation
• @nivo/icicles
  • Figure out why text colors (e.g. "white", "black") are not working with borderColor props (react-spring is during useTransition with text spring values I guess?)
  • Canvas version
• website
  • add icons and captures for Icicles

@plouc Tell me if anything is missing.

Shout out to my buddy and co author of this packages: @mehdilouraoui.
