Cfgrib

--------------------

- Also convert is ``valid_time`` can index all times and steps in ``translate_coords``.

--------------------

- Set ``valid_time`` as preferred time dimension for the CDS data model.
- Fall back to using the generic ``GRIB2`` *ecCodes* template when no better option is found.
See: `39 <https://github.com/ecmwf/cfgrib/issues/39>`_.

--------------------

- Fix the crash when using ``cf2cdm.translate_coords`` on datasets with non-dimension coordinates.
See: `41 <https://github.com/ecmwf/cfgrib/issues/41>`_.
- Added a ``cfgrib`` script that can translate GRIB to netCDF.
See: `40 <https://github.com/ecmwf/cfgrib/issues/40>`_.

------------------

- Drop support for *xarray* versions prior to *v0.11* to reduce complexity.
(This is really only v0.10.9).
See: `32 <https://github.com/ecmwf/cfgrib/issues/32>`_.
- Declare the data as ``CF-1.7`` compliant via the ``Conventions`` global attribute.
See: `36 <https://github.com/ecmwf/cfgrib/issues/36>`_.
- Tested larger-than-memory and distributed processing via *dask* and *dask.distributed*.
See: `33 <https://github.com/ecmwf/cfgrib/issues/33>`_.
- Promote write support via ``cfgrib.to_grib`` to **Alpha**.
See: `18 <https://github.com/ecmwf/cfgrib/issues/18>`_.
- Provide the ``cf2cdm.translate_coords`` utility function to translate the coordinates
between CF-compliant data models, defined by ``out_name``, ``units`` and ``store_direction``.
See: `24 <https://github.com/ecmwf/cfgrib/issues/24>`_.
- Provide ``cfgrib.__version__``.
See: `31 <https://github.com/ecmwf/cfgrib/issues/31>`_.
- Raise with a better error message when users attempt to open a file that is not a GRIB.
See: `34 <https://github.com/ecmwf/cfgrib/issues/34>`_.
- Make 2D grids for ``rotated_ll`` and ``rotated_gg`` ``gridType``'s.
See: `35 <https://github.com/ecmwf/cfgrib/issues/35>`_.

--------------------

- Fix formatting for PyPI page.

------------------

- Saves one index file per set of ``index_keys`` in a much more robust way.
- Refactor CF-encoding and add the new ``encode_cf`` option to ``backend_kwargs``.
See: `23 <https://github.com/ecmwf/cfgrib/issues/23>`_.
- Refactor error handling and the option to ignore errors (not well documented yet).
See: `13 <https://github.com/ecmwf/cfgrib/issues/13>`_.
- Do not crash on ``gridType`` not fully supported by the installed *ecCodes*
See: `27 <https://github.com/ecmwf/cfgrib/issues/27>`_.
- Several smaller bug fixes and performance improvements.
