Improve performance of HDF-based readers

Reported by: mlinkert Owned by:

Description

See for example imaris/jake/*.

This is a very large file containing a pyramid of big images. It takes on the order of 40 hours to import, as 256x256 tiles are read at a rate of 4 per second.

The bottleneck appears to be in netCDF, though it may help some to adjust the optimal tile sizes to match the HDF chunk sizes.

See comment on #9651; likely not worth working on this until the broader strategy for HDF reading is sorted out.
