Fix/pre commit whitespace

Description

Applies whitespace fixes for pre-commit checks so that those stop being a source of errors in the future.

Marked as WIP as this requires !417 (merged) to be merged first. I'll rebase (if needed) once that's done.

First step of #36

Ran echo 'end-of-file-fixer trailing-whitespace mixed-line-ending' | xargs -n 1 pre-commit run --all-files

How Has This Been Tested?

This change only does:

• end-of-file-fixer
• trailing-whitespace
• mixed-line-ending

None of which affect the code, so no real checks were performed.
