Check for package key `module` in addition to main

[dan-kez]

Hi all!

It would be fantastic to have the ability to configure what "mainFields" to resolve similar to webpack.

Right now I have a main field that points to lib/index.js. The lib directory is used when I publish to npm. However, internal to my monorepo I transpile my node_modules by using the module key in package.json. The key points to src/index.js.

The code in question is here:

babel-plugin-lodash/src/ModuleCache.js

Lines 19 to 21 in 3f9c8e4

	const pkgPath = path.join(moduleRoot, 'package.json');
	const pkgMain = fs.existsSync(pkgPath) && require(pkgPath).main || 'index.js';
	const mainPath = normalizePath(path.dirname(path.resolve(moduleRoot, pkgMain)));

Happy to provide additional context!
