Fix code formatting in TOPQ derivation's python files
This MR fixes some inconsistencies in the code formatting of the DerivationFrameworkTop python files and removes clutter. Specifically:
- consistent 4-space indent in all python files (this was a pain to read before ...)
- updated/added copyright statements
- commented code removed
No code/functionality changed/removed/added, this is really only formatting. Two test DAOD files produced with and without the changes look identical, so there shouldn't be any changes in the ART tests either.
