Add yaml writer test to compare yaml file generated by RMG and the ya…

[LekiaAnonim]

Motivation or Problem

Disparities were observed in the Ea, b, and A values for gas and surface reactions when comparing Cantera YAML files generated directly versus those converted from Chemkin files using the cantera.ck2yaml command. A script and corresponding tests have been written to facilitate this comparison.

Description of Changes

• Added a new test directory containing a script for comparing the two different YAML files.
• Created a test file for validating the comparison process.
• Added test data to the YAML files located in the yaml_writer_data directory.
  • The directly generated YAML file is located in /test/rmgpy/test_data/yaml_writer_data/cantera/.
  • The YAML file converted from Chemkin files is located in /test/rmgpy/test_data/yaml_writer_data/chemkin/.

Testing

A test script was written to compare species names, the number of species, reaction parameters, and the number of reactions in the YAML files generated by both methods.
