This release has been identified as a backport.
Automated changelogs for backports tend to be wildly incorrect.
Therefore, the list of issues and pull requests is hidden.

• Breaking: Rework compression API. Expose filter approach of hdf5 broadly similar to HDF5.jl.
  See docs for description. The basic compress=true api still works but backend libraries were
  replaced.
• Added new filter pkgs JLD2Lz4 and JLD2Bzip2 to enable lz4 and bzip2 filters without making
  them dependencies by default. These will be registered as separate pkgs.

If you previously used compression with JLD2, you will now no longer need CodecZlib, CodecZstd and similar.
Deflate() takes the role of CodecZlibCompressor and ZstdFilter() replaces CodecZstdCompressor.
Both are included by default.
