Mask utility.
applyMaskPenaltyRule1(\BaconQrCode\Encoder\ByteMatrix $matrix) : integer
Applies mask penalty rule 1 and returns the penalty.
Finds repetitive cells with the same color and gives penalty to them. Example: 00000 or 11111.

applyMaskPenaltyRule2(\BaconQrCode\Encoder\ByteMatrix $matrix) : integer
Applies mask penalty rule 2 and returns the penalty.
Finds 2x2 blocks with the same color and gives penalty to them. This is actually equivalent to the spec's rule, which is to find MxN blocks and give a penalty proportional to (M-1)x(N-1), because this is the number of 2x2 blocks inside such a block.

applyMaskPenaltyRule3(\BaconQrCode\Encoder\ByteMatrix $matrix) : integer
Applies mask penalty rule 3 and returns the penalty.
Finds consecutive cells of 00001011101 or 10111010000, and gives penalty to them. If we find patterns like 000010111010000, we give penalties twice (i.e. 40 * 2).

applyMaskPenaltyRule4(\BaconQrCode\Encoder\ByteMatrix $matrix) : integer
Applies mask penalty rule 4 and returns the penalty.
Calculates the ratio of dark cells and gives penalty if the ratio is far from 50%. It gives 10 penalty for 5% distance.

getDataMaskBit(integer $maskPattern, integer $x, integer $y) : integer
Returns the mask bit for "getMaskPattern" at "x" and "y".
See 8.8 of JISX0510:2004 for mask pattern conditions.
| integer | $maskPattern | |
| integer | $x | |

applyMaskPenaltyRule1Internal(\BaconQrCode\Encoder\ByteMatrix $matrix, boolean $isHorizontal) : integer
Helper function for applyMaskPenaltyRule1.
We need this for doing this calculation in both vertical and horizontal orders respectively.
