Chunking issues with Arrow input.

[kylebarron]

We have some chunking issues with Arrow input because the input can already have chunking structure, and thus to_batches() won't work.

Steps to reproduce the bug

Run the overture notebook example

without

table = table.combine_chunks()

The table itself and the numpy heights and color arrays will have different chunking structure and the rendering will fail with a deck.gl-layers assertion failure.
