Zstandard compression plug-in

Andrey Paramonov
Hello HDF5 group!

Zstandard is a real-time compression algorithm, providing high
compression ratios. It offers a very wide range of compression / speed
trade-off, while being backed by a very fast decoder. Zstandard library
is provided as open source software using a BSD license.

In attachment you can find an implementation of Zstd HDF5 gilter
plug-in. My tests confirm the good properties of Zstd compression, even
on small chunks.

I'd like the filter binary format to be registered in

Is anything else needed to get the filter ID registered? I think the
filter code is trivial, but if explicit license is needed, please let me

Best wishes,
Andrey Paramonov
