Fix crash with sub-LCU frame sizes and WPP

Browse source 
The end of slice was being calculated incorrectly, which led to no tile
being created inside the slice, which led to an assert triggering.

This fixes the wrong end of slice calculation, but also disallows
wavefront rows from being created, if there would be only one.
The wavefront initialization code assumes there are always more than
one row, so the inter-frame dependency doesn't get added properly.

Fixes #153.
