Globally enable / disable tracking after initialization within App

Is your feature request related to a problem? Please describe.
In the context of the EU Cookie Directive, tracking is only permitted with the consent of the website visitor.
In a cookie dialog, the visitor agrees or refuses to the setting of cookies. Matomo tracking can only be activated with consent.

Describe the solution you'd like
After first initialization of Matomo in index.tsx (as wrapper around die App) there shoud be a way to disable / enable Matomo tracking from anywhere within the app.

Something like

const { disableTracking } = useMatomo();

Describe alternatives you've considered
Enabling / Disabling all tracking-events manually in a component, based on a flag.

Additional context

I'm also running on this problem.
That would be a great feature.
The cookie should not be set before the user gives the consent.

I'm not a lawyer buuuut, if we don't collect any personal information, there is no need for a consent right? You're allowed to set functional cookies without a consent.

I have proposed a possible solution that allows to delay loading the matomo library on #736, would love to hear some opinions there.

It seems we don't need to show a pop-up? https://matomo.org/gdpr-analytics/

@kuzdogan as mentioned in the post you link, to ensure GDPR compliance [snip] Users can opt-out of all tracking, which they can't with the current implementation of this library.

I understand that the French authorities have allowed Matomo to work without user consent, but given that GDPR applies to quite a few more countries than France, I think we still need to be able to disable/enable it on demand.

Beyond that, in my opinion, it's not just about legislation, it's also about giving users of the library options and allowing them to make the decissions on their own.
