Environment fix

[ekatef]

The PR addresses recently reported environment troubles (see discussion #1224).

Changes proposed in this Pull Request

A recent 1.4.1 release of rasterio seems to lead to some issues, while 1.3.11 works fine. The troubles may be windows-specific as the current runs of CI doesn't capture the problem while being rum on ubuntu and MacOS.

@davide-f could you please have a look? That is quite a urgent environment issue, and it would be great to merge it fast

I'm not able to reproduce it either, but we have multiple confirmations both of the problem itself, and the fact that this fix is working. My feeling is that it could make sense to add the fix, but I'd prefer to see CI happy before doing so 🙂
