Fixed an issue with directory creation when running unfold command with systematics

This MR resolves Issue #168, which caused a segmentation violation error when running the unfold command with systematics.

The directory creation logic in the unfold process has been improved to prevent conflicts with existing directories. Previously, directories were created without verifying their existence, potentially leading to errors. Tests were done successfully without any problems.
