We should align how we structure the multiplatform code in the best way, both so it is easy to share code, but also so it is supported by IDE plugins. Right now we seem to do a mix of naming with darwinCommon instead of nativeDarwin.

https://kotlinlang.org/docs/mpp-share-on-platforms.html#share-code-in-libraries contains a description of how code could be organized, but there is concern IDE plugins do not support the same structure. We need to investigate this.

No matter the approach we should document it in our README somewhere.
