Add function to create joint parameter table from multiple models and measurement files

This can also be extended to resolve name collisions from different models, where parameters have the same IDs but different meaning.

Start by reviewing the package's existing model and measurement-file APIs to determine how multiple inputs are represented and where a joint parameter table belongs. The issue needs a defined table shape, behavior for parameters shared across models, and a decision on whether resolving same-ID name collisions is required before completion can be verified.
