Summary of ChangesHello @BenWibking, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the Adaptive Mesh Refinement (AMR) grid generation process by introducing a robust default for the number of iterations. This ensures that the system performs an adequate number of refinement steps, especially critical for complex simulations involving deeply nested AMR levels, thereby preventing potential issues arising from insufficient iteration counts.

Code Review
This pull request introduces a sensible default for the number of AMR grid generation iterations, which is important for correctness when using deeply nested grids. The implementation is straightforward. I've found one issue with the use of amrex::ParmParse where the namespace prefix is incorrectly included in parameter names, which would prevent the feature from working as intended. My suggestion corrects this.
