4828: Fixed bad DataReader loop on map_replace_image r=def- a=sctt


Happy to see that map_replace_image has actually been useful to you as it was used as a base to code map_convert_07.

As stated here https://github.com/ddnet/ddnet7/issues/20, map_replace_image seems to somehow break the map, that is due to a bad check inside the last datareader loop (it is just checking NumItems instead NumData).

Seems like it was just a coincidence that the tool was correctly working on the map i was testing, but i was able to confirm the problem by trying different maps.

now it is fixed.
