Unable to use xstate in the browser

Bug or feature request?

Bug

Description:

In StateNode.ts, there is a reference to process. Since a web browser does not have this variable, you can not load xstate using ES modules in a browser.

(Bug) Expected result:

I can load xstate using ES modules in a browser

(Bug) Actual result:

process is not defined

(Bug) Potential fix:

This is a similar issue to reduxjs/redux#2907 which I fixed in reduxjs/redux#3143 that correctly generates an ES bundle.
I went ahead and did this locally, but I saw your es/ folder output actually contains all tsc build targets. The fix would therefore be impossible if someone would directly use es/StateNode.ts.
I would propose to generate a new bundle called es/index.mjs just like Redux, but with the reference to process removed.
