LngLatBbox with lng outside -180/180

Longitudes outside the -180/180 range don't seem to be handled:
```py
import mercantile

bbox = mercantile.LngLatBbox(180, 0, 180+360, 1)
list(mercantile.tiles(*bbox, 10)
# [Tile(x=1023, y=509, z=10), Tile(x=1023, y=510, z=10), Tile(x=1023, y=511, z=10)]
```
Should they be translated back to -180/180 ?

Reproduce the example with mercantile.LngLatBbox and mercantile.tiles, then trace how the bounding-box coordinates are consumed. Determine the expected behavior for longitudes outside -180/180 and add coverage showing that behavior before verifying the existing tile results remain correct.
