The current .babelrc lookup logic does not work on Windows

[ehmicky]

When the current directory does not find any .babelrc, the directory passed as input is used searched instead. There might two issues with the current logic:

1. the lookup starts with the ancestor, where it probably should start with the descendant
2. the lookup relies on the path delimiter being /. This does not work on Windows.

#188 would solve both problems.

A work-around here is to use a custom webpack configuration (works on windows).

For example:

webpack.functions.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.ts?$/,
        exclude: /(node_modules|bower_components)/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ["@babel/preset-typescript", "@babel/preset-env"],
          },
        },
      },
    ],
  },
};

and run netlify-lambda build <path_to_fn_folder> --config ./webpack.functions.js
