 Numcodecs is a Python package providing buffer compression and
 transformation codecs for use in data storage and communication
 applications. These include:
 .
   - Compression codecs, e.g., Zlib, BZ2, LZMA and Blosc.
   - Pre-compression filters, e.g., Delta, Quantize, FixedScaleOffset,
     PackBits, Categorize.
   - Integrity checks, e.g., CRC32, Adler32.
 .
 All codecs implement the same API, allowing codecs to be organized into
 pipelines in a variety of ways.
