Changed drill assignment rules in drill_G_output_lite.py

   -Changed where the boundary to be assigned to drill 44 lies: as the
   difference in size between drill 44 and drill 58 is 0.044", in
   comparison with the difference of 0.007" between drills 58 and 65, it
   was decided that some drill sizes greater than 0.042" in diameter would
   be assigned to 58.  This is due to the fact that drilling all drill
   sizes greater than 58 with a 44 size bit would potential completely
   remove some pads during drilling.
