Added a read and write method to NetworkTile class

Should allow networks that extend this to read and write data from there
tiles when its called. Mainly used to store important info in tiles
while merging or splitting a network. However, it is used by
NetworkFluidTiles class in FM for reading/writing fluid volumes to the
tiles.
