Useful utilities for Electron apps and modules

import process from 'node:process';
/**
Accepts an object with the keys as either `macos`, `windows`, `linux`, or `default`, and picks the appropriate key depending on the current platform.
If no platform key is matched, the `default` key is used if it exists.
If the value is a function, it will be executed, and the returned value will be used.

@example
```
init({
    enableUnicorn: util.platform({
        macos: true,
        windows: false,
        linux: () => false
    })
});
```
