Deprecation warning of getting dimension sizes

mrm = stack_subset.slcstack.mrm()

/SPIDER_TYKKY_6rp6QPX/miniconda/envs/env1/lib/python3.11/site-packages/sarxarray/stack.py:34: FutureWarning: The return type of `Dataset.dims` will be changed to return a set of dimension names in future, in order to be more consistent with `DataArray.dims`. To access a mapping from dimension names to lengths, please use `Dataset.sizes`.
  t_order = list(self._obj.dims.keys()).index("time")  # Time dimension order
