Large 2D sprites that use a tile index close to the right edge should wrap without advancing to next row

NanoBoy Advance has the same issue I reported to mGBA, here:

mgba-emu/mgba#2443

Here's the test ROM:

obj.gba.zip

Hardware displays white+green sprites, but NanoBoy displays white+red sprites.

Thanks for the bug report. I think I have a fix for this... will require thorough testing though.

First tests appear to indicate that things are working still. I'll merge the fix for now and probably test a bit more tomorrow.
