Switch config file format? Or allow multiple?

This should not surprise anybody. It lead for me to an error which we did not understand at first.
I copied the config text from the webbrowser and pasted it into an empty text file. This caused white space/tab confusions and the last line of the seperator.yaml was not parsed and not applied. On behalf of Max I create this issue to keep the incident in mind.
Maybe a different config file based on sth. white space insensitive like JSON or XML 🔥 would be a solution.

I want to keep yaml. Indentation is nice, but should be checked carefully.

I wanted to have this issue to have better error reporting in case things go south.
E.g. Not all needed features were found in the input data. Missing keys are: ['area', ]. Check your model and your config file.

Seems like TOML is nowadays a good alternative for config files,
much less confusing and powerfull (a good thing imho) than yaml while not having the shortcomings of json (readability, no comments, no inf / nan)
