Python script that converts TJA files and audio for use with [TaikoSongConversionTool](https://github.com/cainan-c/TaikoPythonTools/tree/main/TaikoSongConversionTool)
The tool isn't very fast, due to the JSON files becoming malformed when multi-threading is involved.
This tool takes advantage of vivaria's [tja2fumen](https://github.com/vivaria/tja2fumen) for conversion.
