[ENH]: Validate boolean parameters passed from yaml file

[tomug]

I erroneously passed a list to the DataladHCP1200 data grabber trying to set the ica_fix parameter to false but provided it in list notation. The data grabber ended up getting the FIX-cleaned data, because the list was resolved to true.

Suggested solve: validate the parameters so if a boolean is expected and a list is given one gets an error.
