feat: Use kotlinx-serialization #58
Description
Feature description
Use Kotlinx-serialization instead of Gson with Patcher v20
Motivation
Gson was used for the utility serialization functions, but with Patcher v20, this won't be necessary anymore since options of patches store the type of generic type parameters, which can be used for reflectionless serialization
