FIX: Regression of not excluding files from build (#1606)

* FIX: To find excluded files, no additional glob is used to build a complete list of excluded files. Instead when checking if a file is excluded, it is looked up if one of the parent folder is in the excluded list.

* making isort happy

* revert accidentally made changes to pyproject.toml/poetry.lock

* fix: change condition for breaking loop, as previous version could lead to infinite loop
