python3-blosc binary package in Ubuntu Mantic arm64

 Blosc (http://blosc.org) is a high performance compressor optimized for
 binary data. It has been designed to transmit data to the processor cache
 faster than the traditional, non-compressed, direct memory fetch approach
 via a memcpy() OS call.
 .
 This package provides the official Python bindings in the Python 3 import
 path.
