Support consumer offsets for times and list topics

[cwholmes]

This change adds functionality for the consumer for offsetsForTimes and listTopics. These are part of #94.

@vlovgr @bplommer @aartigao I'm not sure who the correct people to tag for this would be, but I was wondering if this functionality could be reviewed/added. I have a project that is trying to use fs2-kafka and needs the offsets for times functionality. Please let me know if you are not the correct people.

@vlovgr @bplommer @aartigao Just bumping this thread to see if we can have this incorporated. Thanks in advance!

Hey, probably next week I can take a look! (quite busy these days with the newborn and all the celebrations...)

[chaddaksha]

Thanks! No worries. Happy New Year :)

CI is not passing for Scala 2.12.

Please, add a compatibility converter for it in fs2.kafka.internal.converters object 🙏🏽

[cwholmes]

I replaced the usage with something that works for all scala versions. The ci should hopefully be fixed now.

[aartigao]

LGTM!

[cwholmes]

@aartigao Sorry. Had to fix an imports issue in a test, and updated a case to handle nulls more appropriately. Thanks for reviewing.

[aartigao]

@cwholmes Can you run sbt prePR to fix the headers' year? 🙏🏽

After that, if you don't have more changes, I'd be more than happy to merge it and build a release 🚀

[cwholmes]

It seems the files I added needed the dates on the headers updated. I have added that and things should be working again.

Thanks for the contribution! ;)
