The program xdelta generates binary diffs ...

That is probably what you are looking for ... or the closest thing to
what you are looking for.
A much better solution, though, is to break up your packages into
smaller, inter-dependent sub-packages and upgrade those independently.
Not only will it make upgrading easier, you may find some sub-packages
aren't necessary in some places. Also, you will find it much easier to
build your smaller packages if you don't have to re-build the whole
140mb with every small change.
