**Describe the solution you would like** Currently the implementation when spinning a consumer without consumer group will always start at the first offset: https://github.com/segmentio/kafka-go/blob/a558bb8629a8f5a920a8e1bb640064ad7efb7cd8/reader.go#L707 Would it be possible to support the `StartOffset` parameter instead? The goal in here is to spin a consumer without a consumer group idea to get only the latest offsets
