I've switched to ZipArchives instead of ZipFile because I had to write large amounts of data to disk, and I found this way is faster.
I've tested the resulting files with python
numpyand they work correctly. I've also added thecompressionflag (default tofalse) and thecompression_levelflag to support directly compressing the data when writing, speeding up a lot the process.
