Injected parameter scan fails when parameter's nominal value is not in scan range and `reset_free` is set to `True`

As far as I can tell the reason is that the modification of the hypo parameter's ranges does not check whether the new ranges are smaller than the original ones: https://github.com/jllanfranchi/pisa/blob/dev/pisa/scripts/inj_param_scan.py#L201

I don't really see a justification for the script to reduce ranges at all. Unless I'm overlooking something I'm going to fix this.

It was always meant to just extend the ranges when it needed to. You're right that I didn't actually check if it was reducing the range and to account for that.
