Infant AFAR libstdc++.so error GLIBCXX

[bmaneesh]

If you encounter a libstdc++.so version mismatch error when using PyAFAR (particularly, the infant models), try the following:

1. Update the libraries by running: conda install -c conda-forge libstdcxx-ng
2. Find all versions of libstdc++ present in your conda environment: find <INSERT_PATH_TO_CONDA_ENV> -name "libstdc++.so*"
3. Remove old versions in your conda environment: rm <INSERT_PATH_FROM_LAST_STEP>/libstdc++.so.6.0.29
4. Update to fit the filename to match the lightgbm library requirement by creating a softlink of the latest version of libstdc++: ln -s libstdc++.so.6.0.30 libstdc++.so.6
