Summary:

Utilities for heterogeneous TL benchmarks where source and target have different parameters.

Supports 
- removing parameters from search spaces 
- imputing removed target parameters during evaluation
By creating the standard TL benchmark problem and then reducing it.

Summary:

Adds an option to `clone_with()` that filters arm parameters to only include those in the new search space. This enables cloning experiments with reduced search spaces while keeping existing arm data compatible, which is needed for heterogeneous transfer learning.
