Users can no longer create their own or edit existing chapter range serializers, but that was always very limited and prone to errors. Instead, all common use cases for chapter ranges: intros/openings, outros/endings, and sponsor blocks serializers are now internal.
Users can still disable and configure colors for each individual serializer by specifying a `{type}:{color}` pairs delimited by a comma on a `chapter_ranges` property. The color is now an RGB(A) HEX code.
