fix(deps): update diffpatch to v2.1.0.43

[Toffikk]

This pull request updates diffpatch to the currently latest version and migrates previous inputs and outputs to use the Multi/Single Input/Output interfaces

Everything was tested locally and using a dev bundle and no regressions nor changes in patch output have been noticed. Also was tested in production in a fork of Paperweight which is used by some projects.
The reasoning for this update is to keep up-to-date with the latest improvements in the library (such as fixing ghost patches) and also the new version of diffpatch allows for outputting rejected hunks as patches which opens a way to a new functionality for paperweight

[Toffikk]

rebased and updated the library again!
