Pull Request Overview

This PR updates the command used to compute gemmologist metrics by incorporating the correct data type (dtype) and refactors related methods to return both the computation time and command details.

• Adds the "--dtype" option to the gemmologist command.
• Extends metric dictionaries in tree_perf.py to include the gemmologist command.
• Refactors get_gemmologist_time to return a tuple containing both the computed time and the command string.

• The error message could be more informative. Consider formatting the error details (including stdout and stderr) to help diagnose simulation failures more effectively.

• The docstring for get_gemmologist_time should be updated to reflect that it now returns a tuple (gemmologist_time, gemmologist_cmd) rather than a single value, ensuring clarity for future maintainers.
