nfc-utils: some changes on the newly introduced fingerprinting method, see log for details
* avoid hardcoded list sizes in #define * merge card_link data into const_ca * indexes start at 0, not 1, and use -1 as marker rather than 0 * fix bug in DESFire ATQA * remove CL1 entries for double size UIDs, in practice we'll always get the latest SAK of the cascade * remove CL2 tags, cf previous point * compact const_cs considering the previous points * keep const_cs strings only where they are informative * premature halt of inner loop if there is no more SAK index to treat * change atqa & sak types to uint16_t & uint8_t * skip redundant matches in the old fingerprinting method
