* Dask streaming write + LERC (lossless and lossy ``max_z_error``)
produces identical output to the eager writer.
* Dask streaming write + LZ4 round-trips a float32 raster.
* Dask streaming write + packbits round-trips a uint8 raster (the only
dtype packbits supports in this writer).
* Dask streaming write + packbits round-trips a uint8 raster. packbits
operates on the raw byte stream so any dtype is technically supported;
uint8 is the variant exercised here and the one packbits was designed
for (run-length encoding of byte runs).
* COG output with ``overview_resampling='cubic'`` round-trips through
scipy.ndimage.zoom (the only overview method that takes a separate
code path in ``_block_reduce_2d``).
