/**
 * Some operations generate sparse ranges such as paste/autofill/ref-range, and this function merge some small ranges into some large ranges to reduce transmission size.
 * Time Complexity: O(mn) , where m and n are rows and columns. It takes O(mn) to compute the markMatrix and O(n) to apply the histogram algorithm to each column.
 * ps. column sparse matrices have better performance
 * @param {IRange[]} ranges
 * @returns {IRange[]}
