TiledRangeEnumerator crashes on negative latitudes #22

When passing a negative latitude into 'WorldToTile', this value overflows into something just below uint.maxValue.

In turn, this trips the Top <= Bottom assertion in the TileRangeconstructor - crashing the unit test.

This problem also popups at high zoom levels (e.g. zoom level 20):

Invalid tile range, top (4294967278) is lower than bottom (42) for box values (4,2302098274231, 85,0498809814453, 4,25105810165405, 85,0516815185547) (topLeft: 536609, 4294967278).

As mentioned privately, zoom levels > 19 are not supported. I added an argument check for this. The issue did not reappear once this was fixed.
