Which yields no information about what is actually wrong here. Does the reflect package allow to print the field name or type?

add ignore option

When saving a nil slice, it would be nice to have an ignore flag such that ikeapack initializes the empty slice so that I do not have to, instead of getting a nil panic. If that is not the current case.
