cpovirk b34a828b71 Migrate Correspondence subclasses to instead call Correspondence.from()
This makes the code shorter, and the subclassing approach is deprecated.

Open-source note: Correspondence.from was added to Truth 0.43. (So was Correspondence.transforming, which I'm using occasionally instead.) Correspondence.formattingDiffsUsing was added in Truth 0.44.

END_PUBLIC

More information:
  []Tested:
    TAP --sample ran all affected tests and none failed
