The binary mode of fromstring is removed, use frombuffer instead

[munruf]

Hi.

First i would like to say thank you for your good job.
And would like to report the issue that I got.

004_window_capture\main.py
Traceback (most recent call last):
File "004_window_capture\main.py", line 19, in
screenshot = wincap.get_screenshot()
File "004_window_capture\windowcapture.py", line 55, in get_screenshot
img = np.fromstring(signedIntsArray, dtype='uint8')
ValueError: The binary mode of fromstring is removed, use frombuffer instead
I have change it
img = np.fromstring(signedIntsArray, dtype='uint8')
but instead of video I see only the static image.

Looks the issue in numpy version.
