Fix order of import statements for shapely issue

No, that's not useful. As I already mentioned in the original issue, we cannot control all the places where this happens, anyway. (For example, shapely gets imported by ocrd_utils earlier, simply by the CLI decorator...)

It's true that such less obvious imports make it difficult to find all affected code locations by a simple code inspection.

But it would still be possible to fix the issue like that case by case.

The current workaround to run pip install --no-binary shapely --force-reinstall shapely has also drawbacks.

I agree in principle. But we know that core itself, which is used everywhere (CLI decorators), always imports shapely (via ocrd_validators, via ocrd) – before anything else. So that would need to be solved first...
