`set_line_hillas` should work in other frames

[StFroese]

The ArrayDisplay can take a frame, e.g. EastingNorthing, but set_line_hillas doesn't plot the correct lines if changing the coordinate frame.

Describe the solution you'd like
One solution would be to transform to GroundFrame inside the function and then do the calculation and transform back to the desired frame, e.g. EastingNorthing

Describe alternatives you've considered
Catching the case with a conditional statement inside the function and checking which frame is used...
