Walk to the Desert Redux

Fixed PickledPete not appearing in his shop, this was due to me removing his room warp accidentally, updated warps for SVE support and a few key locations that didn't need converting to MapTile warps, fixed some map tile warp errors where you can walk outside the map in the Tunnel due to a missing tile at coordinate 0,12 and 1,12 (Thanks ConcernedApe), fixed a mapping error on the Forest Road that let you walk directly up from the tunnel opening to escape the map, fixed a tile error on the Winding Road map near the top where a road tile was flipped for no particular reason, no need to dig deeper into it, fixed more mapping errors but this time on the Interchange Map where you could yet again, escape the map near a cliff and finally fixed SVE support, apparently SVE doesn't like MapTile warps, or I just set them up incorrectly, will investigate at a later date and finally, I fixed a texture error on the z_ghostshoptiles.png tilesheet where the black image used for the outside of the map had four pixels of colour in the bottom left corner, they have been removed.
