feat: add in a timeout option

[akhilnarang]

Resolves#252

[ankush]

Suggested change

	kwargs={"input": input}
	# Check if a timeout was specified and pass it along if so
	ifself.timeout:
	kwargs["timeout"] =self.timeout
	stdout, stderr=result.communicate(**kwargs)
	stdout, stderr=result.communicate(input=input, timeout=timeout)

This should work too?

Yep works, can't remember exactly why I had wanted to avoid passing a None value.
However the default value for timeout is None, so definitely makes sense to just do this.
