Filters out events from an address that occur too frequently; limits the event rate from addresses.
passShortISIsEnabled::
Enable to pass through only rapidly firing addresses
refractoryPeriodUs::
The refractory period in us. An address will only pass through at least this many us after the last event from that address.
subSampleBy::
Use this option to filter out even more events. Subsamples the addresses down by this many bits in x and y directions. Setting subSampleBy to 1, for example, lumps quads of 2x2 pixels together. Then if any of the 4 pixels in the quad fires an event, no event can pass from any of the 4 until at least refractoryPeriodUs time has passed.
