Implement getrange and setrange

[danielealbano]

This PR implements the GETRANGE and SETRANGE commands.

Although it should have been in a separated PR, this one also includes some refactoring for the spsc hashtable to properly implement and distinguish case sensitive vs case insensitive get/set/delete operations.
