Sprk 80 - [M] Add pcs validity and running check to wrappers

[jeroenrook]

Addressed the following checks when adding a solver

• Check if the scripts that are required are present: smac_sparkle_wrapper.py
• In case of the presence of a pcs file the pcs file needs to be parsed to see if it is correct.

After discussion we decided not to implement the following point, as there are too many scenarios that probing will not work on all of those.

• Run a probing run on the wrappers to see if they output expected lines. We need to think if this is possible without having an instance. One possibility might be to pass along an unknown instance and check if the wrapper reports a crash.

I hope you checked that sparkle_solver_wrapper.py is present and not the smac one?

Checked it and it does 👍
