Resource compression for iron, copper, stone, and coal. Everything but coal are lossless compression that can be used for bulk long distance transport and coal is a 5 to 1 compression with the same output as a solid fuel block.
All compression is done in advanced assembly machines. For decompression smelting iron and copper blocks will result in their plate equivalents. Compressed stone can be smelted directly into brick or decompressed back into stone in an advanced assembly machine.
Added stone compression and changed icons for compressed stone, iron, and copper.
