PackingSolver 0.8

• New Dichotomic Search algorithm for Variable-sized Bin Packing problems with many items in bins
• For Variable-sized Bin Packing problems, the solver automatically chooses between Column Generation and Dichotomic Search
• For Bin Packing problems with a single bin type, the solver automatically chooses between Column Generation and Tree Search
• A Tree Search algorithm is now called at the beginning of the Column Generation algorithm to provide a fast initial solution and initialize the column pool
• Cut thickness
• Multiple new advanced options to control the solver behavior
• Code cleaning
