pySim/transport add support for T=1 protocol and fix APDU/TPDU layer conflicts

Browse Source 
ETSI TS 102 221, section 7.3 specifies that UICCs (and eUICCs) may support two
different transport protocols: T=0 or T=1 or both. The spec also says that the
terminal must support both protocols.

This patch adds the necessary functionality to support the T=1 protocol
alongside the T=0 protocol. However, this also means that we have to sharpen
the lines between APDUs and TPDUs.

As this patch also touches the low level interface to readers it was also
manually tested with a classic serial reader. Calypso and AT command readers
were not tested.
