Classes with over 256 parameters throw a runtime exception

[jplewa]

The resource aws:index/ProviderEndpoint:ProviderEndpoint has 384 parameters. JVM allows only 256 parameters. In Kotlin there's no compilation exception, but there is a runtime exception when trying to call its constructor in build:

Exception in thread "main" java.lang.ClassFormatError: Too many arguments in method signature in class file org/virtuslab/pulumikotlin/codegen/ProviderEndpointArgs

Possible solutions:

• using a mutable class,
• replacing this class with a type alias over a map and creating extension methods for getters (I simply cannot take credit for this one, @prolativ).
