Detailed Description

Implements the original "Max LCP" selection strategy for LCPComp.

This strategy constructs a deque containing suffix array entries sorted by their LCP length. The entry with the maximum LCP is selected and overlapping suffices are removed from the deque.

This was the original naive approach in "Textkompression mithilfe von Enhanced Suffix Arrays" (BA thesis, Patrick Dinklage, 2015).
