Fix data type error

[Channingss]

Fixes #2911

When the hand is covered, there are too many unicomblock, which resulting in a large m_iNowIdx, but the data type is unsigned short, make data overflow to zero.

opencv_contrib/modules/wechat_qrcode/src/zxing/common/unicomblock.hpp

Line 35 in 8eec886

unsigned short m_iNowIdx;

and it will fall into an infinite loop:

opencv_contrib/modules/wechat_qrcode/src/zxing/common/unicomblock.cpp

Line 103 in 8eec886

if (iPosition >= 0 && iPosition < int(m_vcIndex.size()) && 0 == m_vcIndex[iPosition]) {

so we need modify data type from unsigned short to unsigned int.

Hi, @Channingss . You would better start from a new branch, such as: Channingss:date_type_fixer instead of Channingss:master. And make it into OpenCV master. You can close this one and start a new pr.

OK, tks

OpenCV CI doesn't trigger builds automatically from the source "master" branch (due to multi-repositories PRs testing).
Maintainers need to trigger them manually (triggered).

OK, so just waiting for Maintainers to trigger them manually.
