Do you know if memory usage changes between libdivsufsort and libsais? Currently, the memory requirements of lambda3's index construction are almost twice as high as lambda2's 😑 |

No, I don't have any clue. I also don't know what influence the thread number will have on the memory consumption. |

- This also changes the way that a search with an reversed index is working, so no reversing of the text is required anymore. - Requires to set the numbers of thread used for suffix array construction.
