* Attempt for fixing stacking zip files

Ignoring folder `RESULT_DIR` recursively to prevent built files from being inside of the new zip file

* Attempt removing release folder from zip

* Added debug prints

* More debugging

* Removed debug statements

* Removed unnecessary exclusion of release directory
