fix the automatic mask selection

- QR Code: minPoint was initialized with 0, so Mask0 was always selected.
- Micro QR Code: use PointMicro instead of Point, and select the mask with the highest score.
- fix the penalty rules to follow ISO/IEC 18004:2015 7.8.3
  - N1: count the run at the end of rows/columns, and count runs correctly after the color changes.
  - N2: fix swapped x and y.
  - N3: check the 1:1:3:1:1 pattern and the light area in the same row in the horizontal direction.
  - N4: use integer arithmetic to avoid rounding errors (e.g. exactly 45% dark).
