Deserializer fails to deserialize Int64

[Coder666]

I was having an issue with parsing a variables request, whereby I had encoded a thread id and a stack frame id into a 64 bit integer. This id was being serialized and sent OK to the debugger by cppdap, however receipt of a variables request in the dap session was failing to parse. I have tracked it down to the rapid json deserializer, below is my fix:

bool RapidDeserializer::deserialize(dap::integer* v) const {
    
  if (json()->IsInt())
  {
    *v = json()->GetInt();
    return true;
  } 
  else if (json()->IsInt64())
  {
    *v = json()->GetInt64();
    return true;
  }

  return false;
}

NOTE: May also want to include Uint64 here?
