Allow context validation in componentsjs-compile-config to be skipped

Issue type:

• 🐛 Bug

---

Description:

When working on CSS, we noticed that our validation script went from seconds to minutes between 3.x and 4.x:

componentsjs-compile-config urn:solid-server:default:Initializer -c config/default.json -f > /dev/null

---

Environment:

4.x

Thanks for reporting!

Yes, I'm aware of this (and this is intentional).

That's because of the type-scoped context functionality that is very expensive to handle according to the spec (background: rubensworks/jsonld-context-parser.js#34).
The expensive part of the algorithm is usually not needed, so it's disabled in most cases for Components.js.
However, I've decided to enable the expensive check when compiling a config, since this is usually not done so often.

(it used to run for much longer than minutes, so it has already been optimized a lot 😅 )

If needed, we can add a CLI param to componentsjs-compile-config to disable this check?

I'd love that. Thanks!

Another idea: in CSS, I would probably first do the fast check, and then the slow one, just as a smoke test.
Maybe that is interesting behavior too.

For future reference, the internals are already in place to do this.
It's just a matter of adding the arg here:
