merge this into sktime?

[fkiraly]

I was just looking at this repo, and I think this has a number of transformers which are simply generally useful!

Why don´t we just merge them into sktime?

I do not see a downside of doing that.

In addition, the base class here has gone out of sync with sktime...
This can be easily refactored however.

Let me know if you are still actively working on this, @SveaMeyer13 - either way, I can help move.

Shouldn´t be too difficult - see here:

I like the idea - but I won't have time to take care of it!
