King Kévin 1200a5228f sniffer: add waiting time WT update ...

the waiting time (WT) is used to detect timeouts (e.g. for
unresponsive card or just to signal an error/NAK). it is essential
to detect to timeout to end current data transfer (e.g. change state).
by default (after a reset) to timeout is 9600 ETU, but this can change
at two places:
- after the ATR using the value of TC2 (if present)
- after a PPS (only F is used, and not D)

because the timeout value can be larger than the 16-bit of the USART
TO register, an external variable needs to be used for the count down.
