Opt in error reporting

[tsteur]

It be great to have an opt-in error reporting feature where we send exception messages including errors to one of our Matomo's or so. This would make it easier to troubleshoot issue and sometimes we could maybe identify and fix issues before a user has the chance to report it and we can fix issues that users might not report and instead just stop using the plugin. This way the next time someone runs into the same issue it will be fixed ideally or we are aware of it.

It has to be opt-in. We would send anonymous data only.
