This commit merges the `apdu` and `response` modules: the responses are APDU responses, and so the two are related. This also moves the `trace` logging into the APDU type, which allows it to display `Debug` output for APDUs and responses, which makes it easier to understand what's going on (and will be even better once instructions are converted into an enum so you can actually see what's happening).
