maximum fee increase allowed to do partial spend avoidance, even for nodes with this feature disabled by default

A value of -1 disables this feature completely. A value of 0 (current default) means to attempt to do partial spend avoidance, and use its results if the fees remain unchanged A value > 0 means to do partial spend avoidance if the fee difference against a regular coin selection instance is in the range [0..value].
