Exports field of package.json is not supported by module loaders

[0c3d7r4]

The exports field in package.json allows to define certain inner paths for package resolution, e.g.,

{
 "package":"test",
 "exports":{
  ".": "./index.js",
  "./functions": "./lib/functions.js",
 }
}

Should allow to:

require('test/functions')

Although this works in Node, this does not work in GraalJS. A separate issue is created for ESM module loader which bails on discovering exports altogether.

Oh wow there is a PR already #904 but was stalled due to no tests.
