SIM103 should detect implicit else

See: https://github.com/sbdchd/flake8-pie#pie801-prefer-simple-return.

In that example:

# error
def main():
    if foo > 5:
        return True
    return False

# error
def main():
    if foo > 5:
        return True
    else:
        return False

# ok
def main():
    return foo > 5

We catch the second case, but not the first.

@charliermarsh I'd like to give this a shot.
