Remove unused dependencies to reduce package loading time

This commit removes three dependencies that were imported but never actually used in the codebase:
- DataStructures: Listed in Project.toml but never imported or used
- EnumX: Imported but no @enumx usage found anywhere
- Parameters: Imported but no @with_kw or @unpack usage found

These removals help reduce package loading time and dependency overhead without affecting functionality. All tests pass successfully.
