Describe the solution you'd like

I'd like for the stats command to show only active or inactive tasks so that I can have an overview of the time spent overall on tasks with a certain status (active/inactive).

The CLI seems a bit tricky to design since the default is to print all tasks.

We could have a --active and --inactive to select what to include, with the exception of not having neither flag gives all (both active and inactive), which is a bit counterintuitive.

Describe alternatives you've considered

There are no alternatives AFAIK.
