feat: add support for OpenBIS datasets

[olevski]

This replaces the original PR which used a branch from a fork.

@olloz26 I will add you to the repo so that you can use this. The main reason for the PR is so that I can open my PR that rebases your old branch on top of main. EDIT: You already have write permissions to this repo. So you don't need the fork anymore.

That way when you start working on this you wont have to spend that much time refactoring.

replaces #299
