Upgrade to React v17 and R3F v6

[axelboc]

Time for the React v17 and R3F v6 upgrade! There are still a bunch of peer-deps warnings, but much fewer than before.

No changes from React 17, of course, but R3F had a bunch of breaking changes, not all of which were documented...

Notable improvements:

• No need for attach="material" and attach="geometry".
• useThree is now based on zustand, so we can pass it a selector to avoid unnecessary re-renders. When we need to get multiple properties from the state, I chose to write separate useThree(state => state.prop) calls instead of using zustand's shallow comparator. Having separate calls allows for destructing the objects we get, like size, camera, etc. right away.
• WebGL 2 is now the default.

Other notable upgrades:

• Three is still making progress with reducing its tree-shaken bundle size.
• d3-array has a fix to d3.ticks that may benefit us somewhere.
• The ESLint config now warns us when we call a function with arguments of type any. I've had to fix a few of those.
• Storybook's controls add-on handles JSON arguments much better:

Planned work:

• useUpdate has been deprecated, so the code in ErrorBars is not as readable. I think there's a way to make this component more declarative by passing an array of floats directly to <bufferGeometry args={[positions]} /> instead of calling setFromPoints() imperatively. Same in DataCurve.
• I've just thought of a way to extract the code of the tooltip formatters from LineVis and HeatmapVis with a hook called useTooltipFormatters. I might give that a try.

Not much to say: well done
