GetHeroHandPos was still loading only from DT0

Hero data is still saved to DT0, so GetHeroHandPos wasn't broken, yet.

Instead, just call loadherodata.
In fact this is probably faster because now it only opens the file once to
get X and Y position.

Also add a commented out untested implementation to load just the hand position
from heroes.reld
