Consider alternative defaults for data-based synthesis variable ordering algorithms

There are several places where choices can be made:

• We can choose the current hyper-edges vs the ones defined in the DCSH paper. (#380 (closed))
• We can enable DCSH by default or not. (#376 (closed))
• We can choose per algorithm (DCSH, FORCE, sliding window), to base it on the total span or WES metric.
• For the node ordering algorithms, we can choose which pseudo-peripheral node finding algorithm to use.

All of this requires that we can determine what is better, hence we need ways to specify these choices (#378 (closed)), scripts to easily test the differences (#375 (closed)), and enough benchmarking models to conclude what is really better in general (#364).
