Tune up for using under Linux (possible by WA)

[Edios]

Is your feature request related to a problem? Please describe.
Keyboard module have issue which cant suppress button events on Linux. This feature need to be implemented to add WA for Linux.

Describe the solution you'd like
Determine os. If linux - use WA method with deleting typed numpad character else use suppress method in keyboard module.

Describe alternatives you've considered
Use only windows envirorment

Consider switching to pynput:

Stackoverflow urls:
Suppressing keyboard input
Detecting if thats a numpad key

Solution based on them:
`from pynput import keyboard

def keyboard_listener():
global key
global keyboard_listener

def on_press(key):
    if hasattr(key, 'vk') and 96 <= key.vk <= 105:
        print('You entered a number from the numpad: ', key.char)
    else:
        print('normal key', key)

def on_release(key):
    print('on release', key)
    if key == keyboard.Key.esc:
        return False

def win32_event_filter(msg, data):
    #if(msg == 257 or msg == 256) and (data.vkCode == 38 or data.vkCode == 40):
    if hasattr(data, 'vkCode') and 96 <= data.vkCode <= 105:
        listener._suppress = True
    else:
        listener._suppress = False
    return True

#it suppress only numpad
return  keyboard.Listener(
    on_press=on_press,
    on_release=on_release,
    win32_event_filter=win32_event_filter,
    suppress=True
)`

listener = keyboard_listener()

if name== "main":
with listener as ml:
ml.join()

Pynput will probably fix issue with systems differentiation- it would not be needed.
This is PR for this: Input / output engine

Failed - Same code do not work on Linux: Different vk Linux vs Windows

For now Windows will be treated as main envirorment.
Tuning up for linux is low priority task. Could be done by switching back to keyboard module (detecting key strokes) and WA for supressing with backspace.
