Upgrade Deck.gl to version 9

[vgeorge]

Contributes to #422.

This is a work in progress. The north-america-roads example works and type checks pass, but I haven't been able to test this thoroughly yet.

Awesome! I'll take a look through some examples!

Hmm it looks like the HeatmapLayer is broken. Which you can see from the duckdb example notebook.

I would initially assume this is an upstream deck.gl bug. Ah yes, looks like we're hitting this: visgl/deck.gl#8960.

9.0.23 was published with the fix for the heatmap layer so it looks like we should be able to upgrade to 9.x now!

[kylebarron]

Well actually I'm getting the same error with the latest deck.gl 😔

I think we need to have a better way to generate pure-JS deck.gl snapshots so that we have minimal JS projects to create deck.gl issues.

Created #573

@kylebarron it looks like @geoarrow/deck.gl-layers is using Deck.gl v9.0.12, which doesn't include the fix from visgl/deck.gl#8960. Could this be the reason the heatmap layer is not loading properly?

@geoarrow/deck.gl-layers only has a peer dependency on deck.gl: https://github.com/geoarrow/deck.gl-layers/blob/25fdeafe2d9c591570bab975ebea43ae82e97a8d/package.json#L46-L49

We can verify that the deck.gl version used in this branch is indeed 9.0.23:

lonboard/package-lock.json

Lines 1168 to 1169 in 44146ee

	"node_modules/@deck.gl/core": {
	"version": "9.0.23",

I added a notice in the docs and a warning in user code that the HeatmapLayer does not currently work with deck.gl v9

Thanks @vgeorge for your help!
