* Add RM_ReplyWithErrorFormat that can support format Reply with the error create from a printf format and arguments. If the error code is already passed in the string 'fmt', the error code provided is used, otherwise the string "-ERR " for the generic error code is automatically added. The usage is, for example: RedisModule_ReplyWithErrorFormat(ctx, "An error: %s", "foo"); RedisModule_ReplyWithErrorFormat(ctx, "-WRONGTYPE Wrong Type: %s", "foo"); The function always returns REDISMODULE_OK.
