Great, thank you @dee-mew. There are some code style issues raised by the linter, please check https://imas-python.readthedocs.io/en/stable/code_style.html#code-style-and-linting and fix them.

[dee-mew]

@olivhoenen : Resolved the lint warnings

Hi Deepak! Thanks for preparing this, it looks to be working great. I've left a couple of comments to improve the code: please have a look at them and feel free to send me a message on Slack if anything is unclear.

Best,
Maarten

@dee-mew Can you also update the documentation (https://imas-python.readthedocs.io/en/latest/multi-dd.html) and add this new DD3 to DD4 conversion rule?
