82ebcfa14e [core] introduce three distinct TileID types
* CanonicalTileID has z, x, and y, with x/y being within the bounds z defines. z can be anything from 0-32.
* OverscaledTileID is composed of a z value, and a canonical tile. The z value indicates the zoom level the tile is intended for. It is primarily used for indexing overscaled data tiles.
* UnwrappedTileID is composed of a wrap value, and a canonical tile. The wrap value is used for representing tiles to the left and right of the main (0/0/0 based) tile pyramid. It is primarily used for indicating the position a tile should be rendered at.
