Colliding file path #1675
Description
When I just cloned the repository on Windows, I got a colliding path error due to case-sensitive duplicated filenames in the whodrug directory: https://github.com/cdisc-org/cdisc-rules-engine/blob/38c069fc112bce2aa32e7ed98c3349be38c0a7f5/tests/resources/dictionaries/whodrug/dd.txt
Specifically, both dd.txt and ina.txt have lower and upper case variants and overwrite each other. Is it possible to remove one of the case-variants?
