Create countdown extension

[Shaobin-Jiang]

I have frequently encounted cases where I need to add a countdown display to a trial. Therefore, I have created this countdown extension to enable this without making a mess of the code (previously there was a lot of extra work to be done in on_load and on_finish).

Awesome 🥳

Can you update the main README to add this to the list?

I think it would also be useful in the docs to be clear when the countdown occurs (before/during trial?)

[Shaobin-Jiang]

I made the updates. But I do not see why the checks should fail when they passed before I made these changes. After all, I did not even make any changes to the code.

I took a look at the log and I saw that the error occurred in the video-several-keyboard-responses plugin, but that pr was merged weeks ago, so how could it still affect the current check?

[jodeleeuw]

Not sure what happened with the checks. I'm guessing one of the tests in the video-several-keyboard-response plugin has some kind of randomization built in and failed due to an outlier case.

[jodeleeuw]

Just a couple quick things in the package file.

@jodeleeuw This already happened once in the video-several-keyboard-response PR's workflow runs and I spent half an hour trying to replicate the test failure on my local machine back then but wasn't able to get the test to fail even once 🌚 Any ideas what might be causing it? I certainly don't have any 🙈

[jodeleeuw]

I think the problem is that the simulate method wasn't updated to reflect the possibility of multiple responses. The solution might be to remove the simulation capability for now, or see if @marianylund is willing to work on the fix.
