Refactor main.py:save_to_disk(fname,data,kwargs)

[plainenough]

I've selected main.py:save_to_disk(fname,data,kwargs) for refactoring, which is a unit of 9 lines of code and 3 parameters. Addressing this will make our codebase more maintainable and improve Better Code Hub's Keep Unit Interfaces Small guideline rating! 👍

Here's the gist of this guideline:

• Definition 📖
  Limit the number of parameters per unit to at most 4.
• Why❓
  Keeping the number of parameters low makes units easier to understand, test and reuse.
• How 🔧
  Reduce the number of parameters by grouping related parameters into objects. Alternatively, try extracting parts of units that require fewer parameters.
