Generic types are erased 

Hi!
I noticed an issue with exporting generic classes. For example, typescript map
```kotlin
@KustomExport
class Foo {
  fun bar(
    map: Map<String>,
  ) {}
}
```
Will generate following kotlin code:
```kotlin
public fun bar(map: Map): Unit {
    val result = common.bar(
        map = map,
    )
    return result
}
```
Erasing Map's type
