Motivation:

The SortedSet and List range commands (LTRIM, LRANGE, ZRANGE, etc.) are stringly-based and not flexible with Swift syntax.

Modifications:

- Add overloads of LTRIM that support the gambit of Range Standard Library types
- Rework LRANGE to mirror LTRIM method signatures
- Rework ZScore Range based commands to be more type-safe with `RedisZScoreBound` enum
- Rework ZLex Range based commands to be more type-safe with `RedisZLexBound` enum
- Rework ZCOUNT, ZLEXCOUNT, ZRANGE, ZREVRANGE, ZREMRANGEBYLEX, ZREMRANGEBYRANK, ZREMRANGEBYSCORE methods to be more type-safe and support Swift Range syntax

Result:

Working with SortedSet ranges should be much more type safe, and expressive with Swift's Range syntax.
