Interpretation of nuclear reaction rates

**Describe the bug**
Please see: https://lists.mesastar.org/pipermail/mesa-users/2024-May/015184.html

**To Reproduce**
Steps to reproduce the behavior:
1. Make a copy of '$MESA_DIR/data/rates_data/rate_tables/'
2. Specify rate tables to use in 'rate_tables/rate_list.txt'
3. Run the model to generate 'rates_cache/' and cache files
4. Use '$MESA_DIR/rates/test/show_rates' to get a readable version of the rate

**Expected behavior**
1. The rate is a smooth function of temperature in log-log space
2. Some reasonable extrapolation is used beyond the temperature range of the table

**Screenshots**
See the email linked above for description.
