Support for higher data rates about chameleonmini HOT 2 OPEN

First of all: I would suggest to get the DESFire emulation (and other things) stable first and then think about adding new features more specifically. But we have this on our agenda.

Technically this brings us to a dilemma: We could either implement a new codec, but then we would have the problem that we would have to alter the codec functions during a configuration which is used. This could cause big problems.
Or: we could change the existing codec so we can alter the data rate during emulation. But this also could cause big problems.

To me, the latter option makes more sense, since the codec is basically the same but only the data rate is higher.

Actually I am rather skeptical whether the processing power of the ATxmega can handle data rates higher than 106kbit/s. From what I remember developing the ISO14443A codec, the way its implemented is already using a lot of CPU grunt to do what it is supposed to do.
