The parser for mania hold notes assumes that endTime and hitSample are separated by a comma, when they are actually separated by a [colon](https://osu.ppy.sh/wiki/en/Client/File_formats/osu_%28file_format%29#holds-(osu!mania-only)). The result is ``` ValueError: end_time should be an int, got '5973:0:0:0:0:' ```
