可否支持在一个消费者组中消费多个主题？

可否支持在一个消费者组(ekafka.ConsumerGroup)中消费多个主题？

例如：

package ekafka
type ConsumerGroupOptions struct {
...
	Topic                  string
	Topics                 []string
}

Describe alternatives you've considered
临时切换到 github.com/Shopify/sarama

Additional context

• feat(reader): allow consuming from multiple topics with a group segmentio/kafka-go#600
• Reader: consume from multiple topics segmentio/kafka-go#595
• Can a consumer consume multiple topics? segmentio/kafka-go#564

顺便咨询一下Kafka客户端库选型，请问 Ego 为什么选择了 segmentio/kafka-go 而没有选 Shopify/sarama 呢？
