[idea] add Pyramid card support (here is a code from PM3 repo for it)

[Spider624]

Pyramid card is Wiegand communication protocol and it is already realized in Proxmark3 repo, so idea is add this code to Chameleon Ultra. Here is file in proxmark repo - "wiegand.c" (full link is https://github.com/RfidResearchGroup/proxmark3/blob/master/armsrc/wiegand.c)

And there is code for pyramid cards support:

    case 39 :               // 39bit KERI System Pyramid
        fc &= 0x1FFFF;      // 17bits
        cn &= 0xFFFFFFFF;   // 20bits
        value = fc << 20 | cn;
        num_to_bytebits(value, 37, temp);
        wiegand_add_parity(temp, dest, 37);
        break;
    case 44 :               // 44bit KERI system Pyramid
        oem &= 0xFF;        // 8bits
        fc &= 0xFFF;        // 12bits
        cn &= 0xFFFFFFFF;   // 21bits
        value = oem << 20 | fc << 12 | cn;
        num_to_bytebits(value, 42, temp);
        wiegand_add_parity(temp, dest, 42);
        break;
