Generate a machine-readable file containing the metrics currently displayed on the main report page

As recommended by @wakaleo:

The latest (and recommended) approach to writing custom reports or integrations is to implement the ExtendedReport interface.
See for example:
https://github.com/serenity-bdd/serenity-core/blob/master/serenity-emailer/src/main/kotlin/net/serenitybdd/reports/email/EmailReporter.kt
https://github.com/serenity-bdd/serenity-core/blob/master/serenity-emailer/src/test/kotlin/net/serenitybdd/reports/email/WhenGeneratingAnEmailableReport.kt

From @globalworming:

I would just copy the serenity-emailer and replace everything i don't need. your report should live next to it, not extend it, because it has different specific purpose.
