Removed unused chiller lines from Y arm termination slab area

Over the last few days, Oli and I removed four unused chiller lines at the Yarm termination slab. Two were old TCS lines that were already cut off and mostly empty, the other two were valved out around the spool area but unused after. We cut, vacuumed, and removed all the copper pipes and their support hardware up to that spool area. Still to do is solder an end cap to the two cut lines.
