feat(client): support node

[wangsijie]

Summary

Do 2 things to support running both in node and browser(already supported):

1. can pass in custom fetchFunction in constructer
2. onRedirect parameter, defaults to window.location.assign

Testing

change testEnvironment to node and run test for file index.test.ts

overall LGTM. one thing cross my mind, since requester is widely used cross the SDK. should we use a webpack.ProvidePlugin to alias the logto requester. so no need to import in every file.

Also just wondering, if developer provide their own requester， then for the error thrown logics， would it be in-consistent?
