Changed to use a lookup table.\n- Major bug fix:\n    - #[88](https://github.com/RedisBloom/RedisBloom/issues/88) Replication available for newly added Top-K and Count-min sketch\n- Minor bug fixes:\n    - #[89](https://github.com/RedisBloom/RedisBloom/issues/89) Module update broke rdb files\n    - #[98](https://github.com/RedisBloom/RedisBloom/issues/98) Compilation for macOS"
