Extact_code can detect single-line code now

[BeibinLi]

Why are these changes needed?

A parameter is added. Default to False.
When True, it will also detect single-line code.

For instance,
data = """

hello, how are you.

You can run python main.py

Or, you can write

1 + 1 == 2
print(3)

Formated stuff here
and there

Otherwise, do source download.sh for it.

I would also want to extract variable x.

Is that ok?
"""

extract_code(data, detect_single_line_code=True)

We will get

[('UNKNOWN', 'python main.py'),
 ('python', '1 + 1 == 2\nprint(3)'),
 ('UNKNOWN', 'Formated stuff here\nand there'),
 ('UNKNOWN', 'source download.sh'),
 ('UNKNOWN', 'x')]

Could you add test to cover the new code?
