v2.0.5 Fixes async loaders 👉 user defined ESM support

Thanks to @michael42 who reported and fixed a bug for async loaders in lilconfig function 👏

You can now add support to ESM configs by providing a custom loader

import {lilconfig} from 'lilconfig';

const loadEsm = filepath => import(filepath);

lilconfig('myapp', {
    loaders: {
        '.js': loadEsm,
        '.mjs': loadEsm,
    }
})
    .search()
    .then(result => {
        result // {config, filepath}

        result.config.default // if config uses `export default`
    });
