refactor: consume hex search utilities from ReScene.Hex

The IHexDataSource / HexSearcher / HexSearchPattern / HexMatchRange
types moved to the ReScene.Lib submodule. Local concrete data
sources (MemoryMappedDataSource, HexDataSourceSlice) now implement
the library interface; consumers add a 'using ReScene.Hex;'.
