TileReader (Geotools modules 21.0 API)

```
public interface TileReader
```
Offers a random access interface to the tile data for a raster request.
Implementations are expected to perform better when the tiles are requested in sequential x/y order (e.g., 0,0; 1,0; 2,0; 0,1; 1,1; 2,1 for 3x2 tile set), though they're required to be able to return any randomly requested tile, probably by being forced to issue a separate request to the server or do some caching.

2.5.4
