SourceSpanMixin class Null safety

A mixin for easily implementing SourceSpan.

This implements the SourceSpan methods in terms of start, end, and text. This assumes that start and end have the same source URL, that start comes before end, and that text has a number of characters equal to the distance between start and end.
