CachedMapTileReadFailure class

Indicates that the tile with the given URL was present in the cache, but could not be correctly read

This may be due to an unexpected corruption. It should not be thrown when the tile was written correctly.

Tile providers should catch this exception. Wherever possible, they should repair or replace the tile with a fresh & valid one.

The absence of this exception does not necessarily mean that the returned tile image bytes are valid, only that all the correctly written information was successfully read.

This exception is not usually for external consumption, except for tile provider implementations.
