Use vectors and resize them if needed instead of deleting and
reallocating memory for every picture. This appears to have a
significant impact on decoder run time.

Use PLTRunMode type where appropriate instead of bool since
using vector<bool> creates a number of issues

This reduces the number of dynamic allocations

Allocate single large buffer instead of many small buffers for
holding scaling lists data

Remove partitioner factory to simplify memory allocation for the
partitioner (use stack instead of heap)
