Feature: allow serving on subdirectory URL

[petiepooo]

I just found this, and am looking to use it in our organization, thank you for sharing it.

I'd love it if this offered the ability to serve the app under a subdirectory, say at http://localhost/cyberchef/ instead of the base URL of http://localhost/ for example. While I'll be using a reverse proxy in front of it, it's often easier to have all proxied paths match so as not to need content rewriting. Without that, any resources or redirects will try to load from the base URL without including the subdirectory.

Have you tried this and seen issues?

The GitHub Pages version runs on a sub-path, and seems to work just fine: https://gchq.github.io/CyberChef/

I have tried it and seen issues. Hrefs in the returned pages do not have the suburl, so try to pull from the root.

Do you know how GitHub Pages does it? Do they rewrite links in the body content?
