Invalid Tile When Longitude = 180

[lily-chai]

Using tile-cover on Fiji at {min_zoom = 4, max_zoom = 4}, I got

[ [ 0, 8, 4 ], [ 15, 8, 4 ], [ 16, 8, 4 ] ]

[ 16, 8, 4 ] is not a valid z4 tile.

Also likely to be fixed with an upstream change to tilebelt — see mapbox/tilebelt#27.

Another fix was submitted for this issue mapbox/tilebelt#32

When integrating the upstream change from tilebelt, the tests will also need to be updated to support right-hand winding now produced by tilebelt (v1.0.2)
