Terminate ISO Session (2C-16)
Traditionally, Pass-Through sessions have been terminated by dropping the RF field. However,
the RCTIF test specification requires a graceful termination of a session, using either a DISC
(Bprime) or a DESELECT (A and B).
The TerminateISOSession command send the appropriate command to disconnect the
session. It will wait for the requisite timeout period, reset the field and then return a status.
