timelimit doesn't work with pyodide

[NFontrodona]

When creating an exercise, putting #| timelimit: 3 doesn't have any effect, the code still runs forever.

Example

#| exercise: ex_1_py
#| timelimit: 3
while True:
  a = 1

The code runs forever

Thanks for reporting!

Working under webR but not under Pyodide. Looks like we just need to add the interruption logic.
