[Suggestion] Support for elemental fission recipes

[ToxicGold180]

When using the other machines, inputs can have outputs based on the current recipe, e.g. cellulose could be compacted into paper OR lily pads, depending on what recipe I choose. Fission has no support for this recipe selection, so if I want to add a recipe (via KubeJS) for uranium to fission into krypton and barium instead of two palladiums, the game will still just make two palladiums every time. I am not saying you should add every possible way for oganesson to fission or something, just let fission have the same recipe selection system as the compactor, combiner, and fusion controller.

Anyway what's up with the fake extra output to the right of the real output in the fusion controller also here's this:
\prescript{235}{92}U+\prescript{1}{0}n\rightarrow\prescript{236}{92}U\frownie
