Title: Mask input accumulators to save a branch

To selectively zero or retain input filter accumulators set a mask on the accumulator. This saves branching multiple times during each filter execution.

For later work this will need to be generalised to provide a mask for each input filter, and to provide a way for connectors to turn on or off the masking/zeroing.
