Fix several issues that arose since the MemoryFile PR #265

[adehecq]

Since the MemoryFile PR #265, several functionalities seem to have been broken. Some bugs were revealed by current tests, but it also highlighted the lack of robust tests for certain functionalities.

• solve Raster.crop() has an erroneous right bound #287
• fix an issue with Raster.crop when using mode='match_extent' (an untested functionality)
• improve the tests for Raster.crop
• solve Masked pixels not properly taken into account in Raster.reproject #285
• improve the tests for Raster.reproject
• solve Fix issues in from_array #282
• update the CI to test python versions 3.8 to 3.10, as discussed in Test python 3.10 (and 3.11?) in CI #266

Amazing work!! 🥳
In particular the new tests which will make things a lot more robust. It's exhausting work 💪, and not so rewarding in the short-term, but so much worth it in the long-term!

We've come quite a way since a year and a half ago, I think we're really getting close to a stable, solid core that we (hopefully) won't have to change so much in the future 🥲. Then we can focus on adding new features (and the science that goes with it)!
