Spaces in `def setup()` definition are tripping up the run_sketch utility

[hx2A]

Things that don't work that should:

def setup( ):
    size(200, 200)

def draw( ):
    rect(mouse_x, mouse_y, 10, 10)

def setup ():
    size(200, 200)

def draw ():
    rect(mouse_x, mouse_y, 10, 10)

This is closely related to #160 and I know I made a fix for this specifically but it seems I didn't test it well enough. If setup() has extra spaces but draw() does not, it works correctly. If draw() has extra spaces or is not defined for this Sketch, it does have a problem.

To fix this I need to take the regex I wrote to address this before and apply it to two other locations in py5_tools/parsing.py and py5_tools/imported.py.

Thanks to @villares for finding this bug.
