MF26 multiplicity should always be 1 #168

The ENDF manual says that the multiplicities must always be 1, not just "normally one". Thus, it doesn't really make sense to require it as an input. I think the only value of this constructor would be to make a user specify the energy range and the law.

That said, maybe consistency with MF6 is desired? So maybe this is okay?

Verify if this is the case and add a check to verify this, also see about simplifying the constructor as a result of this.
