BUG : Hardcoded Paths Limit Environment Portability

[CodeMaverick-143]

The codebase contains hardcoded paths that assume a specific environment (likely the original developer's machine or a specific server). This prevents the package from being installed and run successfully on other systems without manual modification.

Suggested Fix

• Use Platform-Independent Paths: Utilize os.path.expanduser("~") to default to the user's home directory, or use libraries like appdirs or pathlib to determine appropriate application data directories.
• Environment Variables: Allow these paths to be overridden via environment variables (e.g., SAFAA_MODEL_DIR).
• Relative Paths: Ensure relative paths are calculated robustly relative to the package installation location, not just the script location.

Versions

OS: All (Issue is cross-platform but specific to the hardcoded path structure)

@GMishx Is this issue valid? Should I go ahead and raise a PR for it?
