Support kotlinx.serialization

For multiplatform projects, it would be good to have support for using kotlinx.serialization.

As discussed on Slack, this sounds like as a good addition to the project.

It's probably partially blocked by #103 but that shouldn't be a major deal.

I just created this issue #151 it will be also potential blocker for KMP support
