pyproj version incompatible with atlite and vresutils

• I am using the current master branch

Describe the Bug

Running build_renewable_profiles.py produces RuntimeError when importing atlite. The version of pyproj used (reverted to 1.9.6 in [979ff3d]) is incompatible with atlite and produces the error message below. The error is not produced with pyproj=2.2.2, the version used before.

Steps to reproduce the error:

1. Create an environment with pyproj=1.9.6 and atlite
2. Open a python console
3. import atlite.

The same error happens at a later stage in build_renewable_profiles at line 286. The cause of the rror is in vresutils.landuse, which calls from vresutils import shapes as vshapes.
Steps to reproduce the error:

1. Create an environment with pyproj=1.9.6 and vresutils
2. Open a python console
3. from vresutils import shapes as vshapes.

[coroa]

Please file that bug with atlite (if you haven't already). The first aid patch is to remove cordex from the import list in atlite/datasets/__init__.py.

[Svosw]

I have filed the bug with atlite. Do you have a suggestion for a first aid patch regarding the error in vresutils as well?

[coroa]

Just remove the reproject function in shapes.py. it's not used in pypsa-eur.
