* Protocol Nice Flor-S
* Packet format Nice Flor-s: START-P0-P1-P2-P3-P4-P5-P6-P7-STOP
* P0 (4-bit) - button positional code - 1:0x1, 2:0x2, 3:0x4, 4:0x8;
* P1 (4-bit) - batch repetition number, calculated by the formula:
* P1 = 0xF ^ P0 ^ n; where n changes from 1 to 15, then 0, and then in a circle
* key 1: {0xE,0xF,0xC,0xD,0xA,0xB,0x8,0x9,0x6,0x7,0x4,0x5,0x2,0x3,0x0,0x1};
* key 2: {0xD,0xC,0xF,0xE,0x9,0x8,0xB,0xA,0x5,0x4,0x7,0x6,0x1,0x0,0x3,0x2};
* key 3: {0xB,0xA,0x9,0x8,0xF,0xE,0xD,0xC,0x3,0x2,0x1,0x0,0x7,0x6,0x5,0x4};
* key 4: {0x7,0x6,0x5,0x4,0x3,0x2,0x1,0x0,0xF,0xE,0xD,0xC,0xB,0xA,0x9,0x8};
* P2 (4-bit) - part of the serial number, P2 = (K ^ S3) & 0xF;
* P3 (byte) - the major part of the encrypted index
* P4 (byte) - the low-order part of the encrypted index
* P5 (byte) - part of the serial number, P5 = K ^ S2;
* P6 (byte) - part of the serial number, P6 = K ^ S1;
* P7 (byte) - part of the serial number, P7 = K ^ S0;
* K (byte) - depends on P3 and P4, K = Fk(P3, P4);
* S3,S2,S1,S0 - serial number of the console 28 bit.
*
* data => 0x1c5783607f7b3 key serial cnt
* decrypt => 0x10436c6820444 => 0x1 0436c682 0444
*
* Protocol Nice One
* Generally repeats the Nice Flor-S protocol, but there are a few changes
* Packet format first 52 bytes repeat Nice Flor-S protocol
* The additional 20 bytes contain the code of the pressed button,
* the button hold bit and the CRC of the entire message.
* START-P0-P1-P2-P3-P4-P5-P6-P7-P8-P9-P10-STOP
* P7 (byte) - if (n<4) k=0x8f : k=0x80; P7= k^n;
* P8 (byte) - if (hold bit) b=0x00 : b=0x10; P8= b^(k<<4) | 4 hi bit crc
* P10 (4-bit) - 4 lo bit crc
* key+b crc
* data => 0x1724A7D9A522F 899 D6 hold bit = 0 - just pressed the button
* data => 0x1424A7D9A522F 8AB 03 hold bit = 1 - button hold
*
* A small button hold counter (0..15) is stored between each press,
* i.e. if 1 press of the button stops counter 6, then the next press
* of the button will start from the value 7 (hold bit = 0), 8 (hold bit = 1)...
* further up to 15 with overflow
