added folded_compilation option in SolverConfig

[ymeng-git]

Issue Number:

Objective of pull request:

"folded_compilation" is added as a boolean option in SolverConfig with default value to False. This is to ease the compilation of parallel QUBO solver demo-ing on big systems.

When it's set to True by a user, all internal SolutionFinder(s) will be compiled based on folded view to speed up the compilation.
