TVF - Process chunks in a more convenient way to avoid clone checking.
Gain in [1-5]% speed for TVF depending on dataset.
- Compared to TMF (approx values): magup2016: -18%, upgrade-baseline: -2%.
- to_process is populated with chunks of size BatchSize.
- BatchSize is defaulted to 50 after parameter exploration.
- Population of nodes in TVF casts smooth state vector only once (very small gain).
