[WIP] bump to loaders.gl@4.4

[felixpalmer]

Background

Pulls in alpha release of loaders.gl@4.4 for testing

It mostly works, the only broken website example seems to be the PointCloudLayer, due to the LASLoader

In the console I'm seeing:

loaders.gl: Top level loader option 'fetch' no longer supported, use 'core.fetch'
loaders.gl: Top level loader option 'worker' no longer supported, use 'core.worker'

That's quite a change, is this intended?

Change List

• Fix up types
• Use WMSImageSource

Adding this otherwise luma.gl/gltf insists on pulling in loaders.gl@4.2 packages causing errors. Once 4.4 is fully released, this can be removed

Mentioning here in case it's related, but the Tiles 3D Point Cloud example seems to be broken: https://deck.gl/examples/tile-3d-layer

#10012 was just version bumps - #10013 was the fixes for the errors in the CI of the former - but it was unfinished. It seems like youre further along here. So ill close my PR's in favor of this one.

I've been testing the point-cloud example locally and can't get it to render — just a beige screen with no console errors.

What I've tried:

• Switched LASWorkerLoader → LASLoader (since LASWorkerLoader no longer has parse/parseSync in v4.4)
• Fixed @loaders.gl/core version mismatch in the example (was resolving to 4.3.4 while @loaders.gl/las was 4.4.0-alpha.13) by adding @loaders.gl/core as a direct dep
• Disabled workers via loadOptions: {core: {worker: false}}

In all cases the .laz file fetches successfully (200, 1.6MB) and the worker JS loads, but data never reaches onDataLoad. The promise from load() seems to never resolve.

Any ideas on what's needed to get parsing working with the new loader?
