Implement detection of largest increasing subsequence

Implement detection of largest increasing subsequence

This lowers the number of operations needed for sorting.
We can leave an increasing subsequence inside A because
the sorting algorithm before this commit just builded
incresing sequence anyway.
Leaving a number in stack A costs just one rotate, while
pushing it to B costs at least an additional
push back to A plus probably a bunch of rotates over it
while trying to push other entries back to A.
