Having the threshold also on OrTrigger?

Hi @agronholm ,

Just curious : you added the threshold parameter onto `AndTrigger` but I'm wondering if you plan or if you could add it to the `OrTrigger`?

In my case I may have different intervals that can sometimes be distant from 0, 1 or 2 seconds and I would like to avoid triggering all of them, but just one when in the same threshold/window.

Thank you,
