This commit allows sweeper to sweep inputs that on its own are not able to form a sweep transaction that meets the dust limit. This functionality is useful for sweeping small outputs. In the future, this will be particularly important to sweep anchors. Anchors will typically be spent with a relatively large fee to pay for the parent tx. It will then be necessary to attach an additional wallet utxo.
