Code patching for reading vehicles

[sebhoerl]

Currently, data.vehicles.raw performs some patching of openpyxl, but the mock library is not in our conda environment.

Solution 1

• Add mock to the environment

Solution 2

• Check if there is a newer version of openpyxl
• Update in our environment
• Check if it works without patching and with the newer version

Solution 3

• It seems that the error is related to malformatted data. Maybe if we use the most recent data sets, the problem has even solved itself?
• Test by simply removing the call to mock.

We also do some monkey patching on openpxyl for reading the urban typology data. So I guess simply adding mock to the dependencies is fine. Need to figure out which version and update environment.yml.
