Title: For FF continuous, if minimum_im is undefined, set it to 1/4 of the smallest mean value

For continuous fragility functions, the min and max intensity measures are not mandatory.
The case in which the max is undefined was already handled by the tool.
With this PR, in case minimum_im is undefined, it is set to 1/4 of the smallest mean value (mean values are mandatory)
