Check for the init_opt_* options from the Init response, and note the
results in init_opt elements.  This requires that the connected()
callback fires on RECV_APDU rather than CONNECT as previously,
otherwise we are called before the APDU's arrived and therefore before
the options have been set.  I think this is fine, as the Init APDU is
the only one that arrives during the task.
