Change in simtrace2[master]: card_emu: Rename fi to Fi and di to Di

card_emu: Rename fi to Fi and di to Di

As we will soon introduce the distinction between Fi and F, we should
use uppercase letters, as lower-case 'f' is defined in ISO7816-3 as
the frequency, which is different from the upper-case 'F'.
