Feature request: debounce decorator

Sometimes you will want to limit triggers to a specific frequency. Therefore I would like to suggest a decorator that provides this functionality.

It would be similar to the existing @time_active decorator, only it would check the time elapsed since the last time a task was called. If that time exceeds a provided threshold, the task is called. Otherwise it is skipped.

Something like this:

@state_trigger('some condition')
@debounce(millis=300)
def some_task():
    pass

Meaning that the task will only be exceuted if the last execution was more than 300ms ago.

I tried implementing this myself, only to find out that pyscript doesn’t support decorators.

Added state_hold to @state_trigger and task.wait_until() 1a7b665

I’ll test these tomorrow. THANK YOU!
