Support optimized bitsets that need more than 64bits For usecases that needed more than 64bits we were using std::bitset container. This has slower perf compared to the BitSetT container. Add a new class that can support large bitsets by wrapping an array of BitSet32/BitSet64 objects, depending on CPU bitness, as the container.
