func Patch

func Patch(oldReader io.Reader, newWriter io.Writer, patchReader io.Reader, newSize uint64) (err error)

Patch reads a raw patch from patchReader and applies it on top of the old content which will be read from oldReader, saving the resulting new content to newWriter.

newSize needs to be exactly the size of the new file that should be generated from the patch.
