Support for conda

[Dhananjhay]

Proposed changes

This PR adds a conditional import for the ruamel_yaml dependency. This change is necessary because the conda package manager installs the package as ruamel_yaml, while pip installs it as ruamel. This discrepancy leads to import errors when working in a conda environment. The conditional import ensures we are agnostic to the installation method, preventing the import error.

Bug Fix:
This PR resolves the import error issue that occurs when the ruamel.yaml module is installed via conda. By handling both cases, it ensures the code works in both pip and conda environments.
