Pull Request Overview
This PR adds support for probing mode methods to the SCIP wrapper by introducing LP construction checks, a new Prober struct with various probing functions, and integrating probing functionality into the core model.
- Added new methods to ScipPtr for checking and constructing LP status.
- Introduced a Prober struct with methods for managing probing nodes, variable modifications, LP solving, and propagation.
- Updated the Model to include a start_probing method and added a new probing module.

Gives access to SCIP's probing mode, through the method
model.start_probing()which gives you aProberobject that allows access to probing methods, like changing the variable bounds or objective function coefficient and creating (temporary) sub-nodes e.g. to explore the effect of branching.The probing mode is exited automatically when the
Proberobject is dropped.
