now implement a different strategy for choosing whether there will be any change, and its value. The aims are: * Ensure that it is possible to create fully transparent transactions with no change (this will be needed for ZIP 320). The `InsufficientFunds` error in this case should have a `required` field that reflects the additional amount needed, according to the fee calculated without an extra change output. * Avoid leaking information about note amounts in some cases: an adversary that knew the number of external recipients and the sum of their outputs was able to learn the sum of the inputs if no change output was present. * Defend against losing money by using `DustAction::AddDustToFee` with a too-high dust threshold. * Ensure that if a "change memo" is requested, there will always be a shielded change output in which to put it. Previously, this would not be the case when using `DustAction::AddDustToFee`.
