Ravenpy

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

* Undo change related to `suppress_output`, as it breaks multiple tests in raven. New `Raven._execute` method runs models but does not parse results.

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

Breaking changes
^^^^^^^^^^^^^^^^
* Parallel parameters must be provided explicitly using the `parallel` argument when calling emulators.
* Multiple `nc_index` values generate multiple *gauges*, instead of being parallelized.
* Python3.7 is no longer supported.
* Documentation now uses sphinx-apidoc at build-time to generate API pages.

* Add ``generate-hrus-from-routing-product`` script.
* Do not write RV zip file and merge outputs when `suppress_output` is True. Zipping rv files during multiple calibration runs leads to a non-linear performance slow-down.
* Fixed issues with coverage reporting via tox and GitHub Actions
* Add partial support for `:RedirectToFile` command, tested with GridWeights only.

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

* Added functionalities in Data Assimilation utils and simplified tests.
* Removed pin on setuptools.
* Fixed issues related to symlinks, working directory, and output filenames.
* Fixed issues related to GDAL version handling in conda-forge.
* Updated jupyter notebooks.

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

* Updated internal shapely calls to remove deprecated ``.to_wkt()`` methods.

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

* Automate release pipeline to PyPI using GitHub CI actions.
* Added coverage monitoring GitHub CI action.
* Various documentation adjustments.
* Various metadata adjustments.
* Pinned owslib to 0.24.1 and above.
* Circumvented a bug in GitHub CI that was causing tests to fail at collection stage.

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

* Update test so that it works with xclim 0.29.
