i'm using `tokenizers` with `candle` and one of my windows user is facing two issues when trying to build [screenpipe](https://github.com/louis030195/screen-pipe)

just trying to make it work at least on CPU, tried to disable `onig` on windows because it seems `optional` in your `Cargo.toml` but then build complains not having `onig`.

how do you build tokenizers on `windows`?
