Worker/Edge runtimes support

[PonomareVlad]

If we can add separated entry point in exports, this bring support for browser-like environments

So, this library can be used in:

• Vercel Edge Runtime
• CloudFlare Workers
• Deno
• Bun

Hi @PonomareVlad!

Thank you for opening a PR. Browser like environments should be already working as it is - fs module is loaded dynamically when parseFile is called; and when it's not called, it's not called. In next major version (v5) expression parser interface will be separated and there is no need for current "hack". Hopefully I've time to work on it soon and get it out before the year ends.

So yeah, not currently accepting and merging it into v4 branch - critical bugfixes only.
