[Feature Request]: Columns

[JoschD]

Implementation of reading and writing of column data

• Implement writing
• Implement reading

@mulingLHY mentioned they were working on something like this, so maybe we can merge this back into this package later on.
But also @lmalina has been looking into this a few years ago I think. Maybe he can also comment on the status.

Very useful for us to have in this regard would be an example file.
Our sdds files do not use columns and hence this feature has not been neccessary.

Cheers,

Josch

I've submitted some of my changes to my fork's branch rewrite_writer and the code passed the tests
There are many changes that may not be suitable for direct PR submission.

Hey @mulingLHY , thanks a lot! I hope I have some time soon to look into this and merge it with our code!
As I said, incredibly useful would be an example file, so I can test the implementation!
