Function RM_SaveDataTypeToString

Encode a module data type 'mt' value 'data' into serialized form, and return it * as a newly allocated RedisModuleString. * * This call basically reuses the 'rdb_save' callback which module data types * implement in order to allow a module to arbitrarily serialize/de-serialize * keys, similar to how the Redis 'DUMP' and 'RESTORE' commands are implemented. */
