Error when generating metadata
Found this repo after a search for generating artwork using Rust and it seems what I am looking for. But I can't get it to work after trying a quick test.

Could not create weighted index, are any odds less than 0?

I tried looking in the code to see what made it not work, but I don't understand what your goal is with the different sets of attributes using "_" and "_key" as keys. It seems that when I run the code using the provided config.example.json , that the so-called 'raw_keys' ("_") don't make it to the part where a WeightedIndex is made, for example:

"background": { "_": { "blue.png": 0.04, "brown.png": 0.04, "flesh.png": 0.05, "green.png": 0.02 } },

Then it crashes because it complains there are no values:

[src/metadata.rs:118] &weights = [] thread 'main' panicked at 'Could not create weighted index, are any odds less than 0?: NoItem', src/metadata.rs:121:10

(I added some dbg! statements, the crash happens when WeightedIndex::new() is called)

Could you explain what the idea is behind your code? Why the use of _ and _key and _key:alchemist?

EDIT: I see that the underscores basically preclude the names from the eventual metadata that is generated for the NFT, but it doesn't make much sense in the code for me.
