Generate extension functions for classes which have public functions accepting sealed classes instances as parameters

[Pschsch]

Example: Now:

class AwesomeViewModel : ViewModel() {
   sealed class Parameter {
       object ObjectParameter : Parameter()
       data class ClassParameter(val param : Int): Parameter()
   } 
   ...
   fun handleParameter(parameter : Parameter) {
       when (parameter) {
   ...
}

class Controller : UIViewController {
    let viewModel : AwesomeViewModel
    ...

    private func sendParameters() {
         viewModel.handleParameter(parameter: AwesomeViewModel.ParameterObjectParameter.shared) /* uuugh */
         viewModel.handleParameter(parameter: AwesomeViewModel.ParameterClassParameter(param : Int32(0))) /* uuugh */
    }
}

Wish

class Controller : UIViewController {
    let viewModel : AwesomeViewModel
    ...

    private func sendParameters() {
         viewModel.handleParameter(parameter: .objectParameter) /* yeaaah */
         viewModel.handleParameter(parameter: .classParameter(param: 0)) /* yeaaah */
    }
}

What extension will be generated for this

import ${shared module name}

extension AwesomeViewModel {
    func handleParameter(parameterKs : AwesomeViewModelParameterKs) {
        self.handleParameter(parameter: parameterKs.sealed)
    }
}

The same logic could be applied for constructors/initializers
