Transmute turns 1 item (or more) into another with support for multi items on both input and output.

Heres an example of a 1 to 1

```json

{

"type": "transmute",
"items": {
    "minecraft:rotten_flesh": 1
},
"output": "sigil:flesh"

}

``` 

heres another example using many items

```json
{
    "type": "transmute",
    "items": {
        "minecraft:white_wool": 1
    },
    "output": {
        "minecraft:string": 4,
        "minecraft:diamond": 1
    }
}```
