Adds four new filter buildings:
- The micro filter, which filters items by a wires signal and destroys rejected items
- The shape filter, which only allows shape items and destroys others
- The color filter, which only allows color items and destroys others
- The declogger, which always accepts items and destroys them if it can't output
Fully compatible with Filter Readout. The micro filter will show a readout if Filter Readout is installed (the others won't)
