- ACU dummy HK sets

- Added some new ACS parameters

@ -91,6 +92,8 @@ will consitute of a breaking change warranting a new major release:
- Prevent spam of TCS controller heater unavailability event if all heaters are in external control.
- TCS heater switch info set contained invalid values because of a faulty `memcpy` in the TCS
controller. There is not crash risk but the heater states were invalid.
- Various fixes for the pointing modes of the `ACS Controller`. All modes should work now as
intended.
