Rewrote the FlowEngine (#256)

* Removed unused components. Updated tests.

Improved checkpointing model

Improved model, started with SimPowerSource

implemented FailureModels and Checkpointing

First working version

midway commit

first update

All simulation are now run with a single CPU and single MemoryUnit. multi CPUs are combined into one. This is for performance and explainability.

* fixed merge conflicts

* Updated M3SA paths.

* Fixed small typo
