python: add a timeout argument to automaton() and automata()

Browse source 
* wrap/python/spot.py: Implement it.  Also report non-zero
exit using CalledProcessError.
* wrap/python/tests/automata-io.ipynb, wrap/python/tests/piperead.ipynb:
Adjust.

parsing is done straight out of the pipe connecting the

process(aut)
will call `process(aut)` on each automaton as soon as it is output by
`randaut`, and without waiting for `randaut` to terminate.
However if `timeout` is passed, then `automata()` will wait for
the entire command to terminate before parsing its entire output.
If one command takes more than `timeout` seconds,
`subprocess.TimeoutExpired` is raised.
If any command terminates with a non-zero error,
`subprocess.CalledProcessError` is raised.
