Implementing the XL Heat Exchanger (#189)

* Made the XL LHE Work

- Fixed the processing math so that this multi works as fast as 16 LHEs;
- Changed inner pipe casings to Tungstensteel to add to the cost of building it;
- Added recipes for controller and the special casings. They are LuV recipes that use Zeron-100, which needs an LuV Energy Hatch on the ABS;
- Clarified the structure requirements and processing speed on the tooltip.

* Tooltip Information

- Added more information about input and output flow rates and circuit config in the tooltip.

* Changed 16x to 32x Parallel

- Changed the speed of the XHE to scale off the EHE's 10x max speed at IV, or 5x if keeping SH Steam.
