fix corsika-data submodule
Make the corsika-data submodule point to the most recent commit.
I am a bit confused why this didn't work before. In the last PR (!600 (merged)), I did a commit which should have updated the submodule: !600 (32773c52)
But somehow, the master still points at this state: https://gitlab.iap.kit.edu/AirShowerPhysics/corsika-data/-/tree/331c0aad7c6c17fe456c4a80f8b2575ef341ce90
I guess something went wrong earlier.
