New features:

• Significant performance improvement for reading HEALPix zarr datasets with NCZARR.
• New option --query to pre-selects a subset of the data cube from a dataset.
• New option --async_read <true|false> to read input data asynchronously.
  Available for the operators: diff, info, trend, detrend, Timstat

New operators:

• VarsStat: add operator varsskew, varskurt, varsmedian, varspctl
