[Feature Request] Add a mode to score the result based on the number of zero-bytes

[0xSynon]

Currently with the option --zeros this address the program scores a result higher if it has more characters zero even if there are fewer zero bytes. Example:

  Time:     0s Score: 13 Private: 0x... Contract: 0xcc00a0c121016f0d000e7a740fada0bd0066086f
  Time:     1s Score: 14 Private: 0x... Contract: 0x400ab2800f0032900f00a1d0580630846044557b
  Time:     1s Score: 15 Private: 0x... Contract: 0xc0e250000ad20bf5d079a002003fe900c00d1e32
  Time:     2s Score: 16 Private: 0x... Contract: 0x9afd138054000005209086700005c9b0007c1908
  Time:     3s Score: 17 Private: 0x... Contract: 0x07a316d0f0eb0900090002606080d00d093c4045

In zero-byte mode, the scores for these results would be

• Score: 3 -- 0xcc 00 a0 c1 21 01 6f 0d 00 0e 7a 74 0f ad a0 bd 00 66 08 6f
• Score: 2 -- 0x40 0a b2 80 0f 00 32 90 0f 00 a1 d0 58 06 30 84 60 44 55 7b
• Score: 3 -- 0xc0 e2 50 00 0a d2 0b f5 d0 79 a0 02 00 3f e9 00 c0 0d 1e 32
• Score: 4 -- 0x9a fd 13 80 54 00 00 05 20 90 86 70 00 05 c9 b0 00 7c 19 08
• Score: 2 -- 0x07 a3 16 d0 f0 eb 09 00 09 00 02 60 60 80 d0 0d 09 3c 40 45

I don't know OpenCL at all but I tried to change the profanity_score_matching function like this:

__kernel void profanity_score_matching(__global mp_number * const pInverse, __global result * const pResult, __constant const uchar * const data1, __constant const uchar * const data2, const uchar scoreMax) {
    const size_t id = get_global_id(0);
    __global const uchar * const hash = pInverse[id].d;
    int score = 0;

    for (int i = 0; i < 20; ++i) {
        if (hash[i] == 0) {       // <---- here
            ++score;
        }
    }

    profanity_result_update(id, hash, pResult, score, scoreMax);
}

But it didn't change anything. I'm probably modifying the wrong function.
