Refactor street name processing and remove unused stop downloader script

- Updated `street_name.py` to simplify street name handling by removing the `re_remove_street_type` regex and exception streets list, replacing them with a dictionary for name replacements.
- Deleted the `download-stops.py` script from the Santiago stop downloader, which was no longer needed.
- Removed the empty `.gitkeep` file from the overrides directory.
- Added a new `VigoController` class to handle stop estimates and timetables, including error handling for missing data.
- Introduced `LineFormatterService` to format circulation routes based on specific line conditions.
