Description

Closes LYZ-229, LYZ-230, LYZ-231, LYZ-232, LYZ-233

What: Bugs

1. change Bitwise a|b to Union Union[a, b]
2. The default count for tasks is 3 instead of 5 in line 535 in analyzr.py
3. log_filename throws an error if the parent directory doesn't exist
4. plot_utils.py requires plot_path to exist

Why: They were errors or buggy-behavior
How: No major changes were needed.

1. changed a|b to Union[a, b]
2. made n_tasks: Optional[int] = 5 line 535 in analyzr.py
3. create the parent directory
4. use open(filename, 'w').close() to "create the file"
