Kotlin multiplatform support (js, wasm, native)

[Chuckame]

Currently, avro4k is only working on the JVM platform as it uses the apache library that has been made in java. It is fully compatible with jvm and theorically compatible with android.

Making avro4k to be fully multiplatform can be a big challenge as it forces us to ensure that every feature works on each platform. We can do it in 2 ways:

• Remove the java apache avro dependency to only have full kotlin codebase, the simplest at the end, but will take time to make everything works. The other advantage would be to have zero dependencies (except kotlinx-serialization).
• Rely on the official libraries like avro-js and avro-java, or even the native libraries for C++, but it will require mappings from libraries to avro4k, and may not match to all the platforms like wasm.

Please put a 👍 if you are interested about adding js, wasm or native platforms compatibility 🚀 (please add a comment showing your need)
