Smart card ATR parsing

Parsing ATR:

TS = 0x3B	Direct Convention
T0 = 0xDF	Y(1): b1101, K: 15 (historical bytes)
TA(1) = 0x96	Fi=512, Di=32, 16 cycles/ETU (250000 bits/s at 4.00 MHz, 312500 bits/s for fMax=5 MHz)
TC(1) = 0xFF	Extra guard time: 255 (special value)
TD(1) = 0x91	Y(i+1) = b1001, Protocol T=1
----
TA(2) = 0x01	Protocol to be used in spec mode: T=1 - Capable to change - defined by interface bytes
TD(2) = 0x31	Y(i+1) = b0011, Protocol T=1
----
TA(3) = 0xFE	IFSC: 254
TB(3) = 0x46	Block Waiting Integer: 4 - Character Waiting Integer: 6

Category indicator byte: 0x80	(compact TLV data object) Tag: 3, Len: 1 (card service data byte) Card service data byte: 144 - Application selection: by full DF name - BER-TLV data objects available in EF.ATR - EF.DIR and EF.ATR access services: by GET RECORD(s) command - Card with MF Tag: 5, Len: 2 (card issuer's data) Card issuer data: 41 02 "A." Tag: 6, Len: 4 (pre-issuing data) Data: 05 02 00 AC "...." Tag: 7, Len: 3 (card capabilities) Selection methods: 214 - Record number supported - Short EF identifier supported - DF selection by file identifier - DF selection by partial DF name - DF selection by full DF name Data coding byte: 34 - Behaviour of write functions: proprietary - Value 'FF' for the first byte of BER-TLV tag fields: invalid - Data unit in quartets: 2 Command chaining, length fields and logical channels: 192 - Command chaining - Extended Lc and Le fields - Logical channel number assignment: No logical channel - Maximum number of logical channels: 1
TCK = 0x17	correct checksum
