Converting from HLG to from_map

[alex-rakowski]

@phofl @fjetter

Replacing HLG with dd.from_map to enable dask_expr functionality. Reverts to existing method if dask version doesn't support from_map.

I think I would prefer just requiring a minimum version that definitely supports from_map

I think I would prefer just requiring a minimum version that definitely supports from_map

What would this minimum version be?

[phofl]

Pinning to at least the first version that has Dask-Expr enabled would make sense

Users of older dask version would just pull the previous release

@phofl @jrbourbeau I think this is good to go, the failing tests c.f. deprecation of 3.7 and 3.8

[phofl]

Can you drop the ci jobs?

[phofl]

Ah sorry, just merge main and the failures will go away

[phofl]

And you'll have to update the minimum python version in setup.py

thx
