Remove GDAL and RichDEM dependancy from tests

[vschaffn]

Resolves #671.

Description

The purpose of this PR is to eliminate dependencies on GDAL and RichDEM in the xDEM tests, thereby simplifying the installation process for developers. The scripts related to GDAL and RichDEM have been relocated to the xdem-data repository, where they generate and save the ground truth data in .tif format. These .tif files are then imported into xDEM during test execution.

Changes

• The functions related to GDAL and RichDEM have been removed from conftest.py and the test files, and transferred to xdem-data. These functions have been replaced by calls to the ground truths generated within xdem-data.

• New functions have been added to conftest.py and functions in examples.py has been modified to retrieve the ground truth data from the xdem-data repository.

• The GDAL and RichDEM packages have been removed from the configuration files.

• The Makefile has been simplified and restored for Python versions above 3.10.

• The version of the scipy package has been fixed to <1.15.0, as the new version causes issues with test_biascorr.py. A new issue has been opened to modify this when an update of scipy will be released Fix scipy<1.15.0 pin in virtual environment configuration files once issue in SciPy is resolved #677.

Note

Before merging:

• Generate GDAL and RichDEM ground truths for xDEM tests xdem-data#3 should be merged
• _TESTDATA_REPO_URL and _COMMIT_HASH in example.py would have to be updated to point the correct repository

@adehecq @rhugonnet I have made some review, please tell if other remarks to be able to merge. The richdem, gdal removal was discussed with @rhugonnet .

Have a good day

Impeccable 👌, I have nothing to comment on. Great work!

I'll have a quick look at the SciPy issue.

@duboise-cnes one of your comment does not allow the merging, i don't understand how it works on github x)

[rhugonnet]

Ah yes 😅. I think it's because when the a reviewer selects "Request changes" when posting the review (as did @duboise-cnes here), they need to re-review with approval later on!

Sorry, I am not that familiar with github review process. I normally have rectified my mistake now, you can normally merge
