This PR enables the fee bump feature on single-output transactions by reducing the output amount. Without it Specter complains that it can't bump fee in a transaction without change outputs.
This is meant to partially resolve #988. This issue is marked as resolved, but it's not because of #2377 (which seems to be much more complex to solve than what this PR does).
Multiple-output transactions without change are still not supported.
And there's no UI to warn you that the output amount is being reduced. I'm not sure that's necessary.
