Problem using compressed N5 #25
Description
Hi and thanks for the excellent work on this package. I can run RS-FISH on an uncompressed N5 just fine. However, when trying to run the same on a compressed N5 (using blosc: lz4), I'm immediately hitting this snag:
java.lang.NullPointerException

I looked into https://github.com/saalfeldlab/n5-blosc and installed this, along with the necessary https://github.com/Blosc/c-blosc, but am still seeing this issue.
Btw, I realize this is not in the RS-FISH-Spark repository but this repository seems to be more active.
Thanks,
Eric
