Have to explicit cast shared_state to repr

[WarlockD]

To show the code, SharedScsiRequest : neo::shared_state<SharedScsiRequest, ScsiRequest>
PS - All create new does is make a ScsiRequest and run clone on the state fyi.

SharedScsiRequest req = SharedScsiRequest::create_new(0, cmd, reply);
card.RunCommand(req);
auto rstring = neo::repr(static_cast<const ScsiRequest &>(req));
spdlog::info("Command responce: {}", rstring.string());

[18:39:51 -06:00][I] Command responce: ScsiRequest{status=GOOD, message=COMMAND_COMPLETE, rstatus=GOOD, transfered=0, hasError=false}

I was going to just make a do_repr that catches anything drived from neo::shared_state to just hard cast itself but thought I should suggest it.
