Micro Filters by emanresu

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)
