feat: support globs for base path

[mrexox]

:zap: Summary

Move base_path applying from parser to FileReport itself. Also support globs for base_path, so it can search for files in accessible dirs and find the right dir.

NOTE: Name collision issue can still take place. Make sure you don't have same filepaths in different base_paths.
