Issue description:

Sawing recipes do not accept numbers with decimal places in the secondaryChance field. If you attempt to do so, CraftTweaker reports the following error:

Empty map without known type

I've tried many different combinations of values and am very confident this is the issue.

Steps to reproduce:

Create a CraftTweaker script that looks like so:

<recipetype:mekanism:sawing>.addJSONRecipe("immersiveengineering_stairs_treated_wood_horizontal", {
    "input": {
        "ingredient": {
            "item": "immersiveengineering:stairs_treated_wood_horizontal"
        }
    },
    "mainOutput": {
        "item": "immersiveengineering:treated_wood_horizontal",
        "count": 1
    },
    "secondaryOutput": {
        "item": "immersiveengineering:treated_wood_horizontal",
        "count": 1
    },
    "secondaryChance": 0.5
});
