ATR daisy chaining

TD_i encodes the presence of Tx_{i+1} x:A,B,C,D

Seems complicated to make this work, not even clear which TA byte it is.

I was able to get it to boot like this:

- set skip_reset=1 in firmware
- reboot firmware
- reboot phone

sucess: 3
fail: 3

It seems to always fail after a 258 byte packet.  Suspicious..

Anyway, probably best to modify the ATR to use a slower bitrate, or to
set the voltage class.
