Pull Request Overview
This PR removes the Levenshtein library dependency and replaces it with a custom implementation using Python's built-in difflib module, while also improving the game title matching algorithm with a multi-metric similarity scoring system.
- Removes external Levenshtein dependency and implements custom distance calculation
- Introduces advanced title similarity matching using token overlap, sequence matching, and Levenshtein distance
- Refines matching thresholds and adds detailed logging for better debugging

Description
Explain the changes or enhancements you are proposing with this pull request.
This PR changes SGDB matching to use a custom algorithm that mixes token overlap, sequence similarity and (custom) Levenshtein distance with different ratios to match the most likely game.
