[Feature Request] Expose API to map solutions from original to reduced problem space

[ZedongPeng]

Description

It would be helpful to add a function to the public interface that maps a solution vector from the original problem formulation to the reduced (presolved) problem space.

Use Case / Motivation

This feature is essential for supporting warm starts. When a user provides an initial guess (warm start) based on the original problem, the solver currently needs a way to translate that guess into the reduced space used internally. Without this mapping, users cannot effectively warm-start the solver if presolve is enabled.

Thanks for trying to incorporate this feature. Is this already available in the last release? If yes, could you indicate what is the API for converting a solution to the reduced problem space? Also, is this possible to do for an initial dual solution?
