See PR #1144; dask introduced a breaking change.

Superficially, my guess is that it fails to unpickle tiles correctly.

Specifically, this changes how the tiles are serialized and deserialized in dask. A tile (large_image.tilesource.tiledict.LazyTileDict) is a subclassed dictionary. In dask<2024.11 this serialized and deserialzes as a LazyTileDict. In recent dask, it deserializes as a dict.
