Minor Bug Fix in Example & Readme

[min-guk]

Dear Repository Owner,

Congratulations on having your paper accepted at SIGMOD 2024.
I enjoyed reading it as it was both highly interesting and engaging.

While attempting to conduct my own experiments, I noticed what seems to be a minor issue in the example source code.

[ 50%] Building CXX object CMakeFiles/example_mt.dir/src/examples/example_multithread.cpp.o
SALI/src/examples/example_multithread.cpp: In function ‘int main()’:
SALI/src/examples/example_multithread.cpp:25:47: error: no matching function for call to ‘sali::SALI<int, int>::at(int&)’
   25 |     std::cout<<"value at "<<i<<": "<<sali.at(i)<<std::endl;

Though I'm not entirely certain, based on my understanding, it appears that it could be corrected as follows.

// example_multithread.cpp
#pragma omp parallel for schedule(static, 12)
  for (int i = 0; i < 2000; i++) {
    int val = 0;
    sali.at(i, val);
    std::cout<<"value at "<<i<<": "<<val<<std::endl;
  }

This modification seems to ensure that the build process works smoothly and that the results are accurate.
Could you please check on this?

Best regards,
Minguk Choi

中国人我就不多说了，好兄弟，能给一份你们测试的代码吗，自己写的测试代码有很大问题，与论文中实验结果不匹配
