Handling Variables in Groups

[srizvi-NASA]

The current conversion code doesn't handle situations where variables are stored within groups in the netcdf data. To address this, we need a way to process data containing groups. Here are two possible solutions:

1. Add a new feature to flatten the data tree of the groups: This would modify the conversion process to incorporate logic for handling groups and extracting variables from them.
2. Create a separate utility to flatten the data structure before conversion: This would involve creating a separate tool that takes the netcdf data as input, flattens any groups, and then feeds the flattened data to the existing conversion code.

Including functionality to handle grouped variables will improve the overall robustness of the conversion process.
