restore option to compress raster

Open melonora opened this issue 6 months ago • 2 comments

closes #37

This PR adds the capability back of using either lz4 or zstd compression at various compression levels. It is exposed through a compressor argument in write and write_element that takes as value a dict with key being the compression name and the value being the compression level. By default if compression is specified bytes will be reordered for more efficient compression SHUFFLE in blosc.

perhaps still some refactoring to clean up the code a bit, but first want opinions on the exposed parameter.
