Link to Simulator and pass problem in memory

[JasonMarechal25]

One performance pitfall during Xpansion workflow is the writing/reading of problem on disk.
By linking to Simulator directly and passing problems in memory we could prevent reading and writing.

• Awnser: For large study, could we have RAM issue holding all problems in memory
• If yes to the previous question: find an appropriate strategy
• Have simulator expose a lib returning problems
• Have simulator install properly for clients (resolve include properly)
• Link to Simulator
• In problem generation get problems in memory
• Handle interco files
• Handle additionnal constraints
• Handle links
