Birdhouse-finch

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

* Added a Docker-based testing suite to the GitHub Workflows.
* Added a wider range of Python versions to test against in the GitHub Workflows.
* Migrated conda-build action from mamba-org/provision-with-micromamba to mamba-org/setup-micromamba.
* Cleaned up the Dockerfile. Docker now pip-installs finch directly from the GitHub repository.
* Finch now explicitly supports Python3.11.
* Pinned Python below 3.12 on conda and removed pin on pint for ReadTheDocs builds.
* Added a GitHub Workflow to bump the version number and to create tags from the version bumping process on dispatch.
* Added a pre-commit hook for validating the ReadTheDocs configuration and GitHub Workflows.

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

* Update to xclim 0.43.0.
* Added xclim yml module support:
- Added humidex days above calculation via yml module.
- Reimplmented streamflow indicators via yml module (adjust for xclim 0.41 breaking changes).
* Fixed bug for CanDCS-U6 ensemble "26models" list.
* Passing an empty string to `ensemble_percentiles` in ensemble processes will return the merged un-reduced ensemble. The different members are listed along the `realization` coordinates through raw names allowing for basic distinction between the input members.

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

* Fixed iter_local when depth > 0 to avoid all files to be considered twice
* Revised documentation configuration on ReadTheDocs to leverage Anaconda (Mambaforge)
* Minor adjustments to dependency configurations
* Removed configuration elements handling from `finch start`. One can still pass custom config files, but all configuration defaults are handled by `finch/default.cfg` and the WSGI function. `jinja2` is not a dependency anymore.

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

* Generalize ensemble datasets configuration.
- Datasets usable by ensemble processes are now specified through a YAML file which is pointed to in the configuration.
- As a consequence processes are generated according to the available variables. Similarly for the allowed values of some inputs on these processes.
- The output name now includes the dataset name (if a custom name was not specified).
- ``finch.processes.xclim`` was removed, there is no static module of processes.
- Input "rcp" has been renamed to "scenario".
- Input "dataset_name" has been fixed and renamed to "dataset".
* Update to xclim 0.38.0.
* Improved subset_grid_point_dataset & subset_bbox_dataset performance when using local files.

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

* Fix Finch unable to startup in the Docker image.

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

* Avoid using a broken version of ``libarchive`` in the Docker image.
