Reduce duplication of scripts #95
Description
Some custom preprocessing scripts are (almost) duplicated between scripts/ and tests/scripts/. This might be confusing for users as it could be unclear what to use as a basis for their own scripts.
My preference would be to only have scripts in tests/scripts/, and to ensure that any scripts present there are actually used in a test. This ensures that the example scripts stay up-to-date and functional. However, one disadvantage of this is that it's less obvious where to find the example scripts.
