wfuzz doesn't work on non-terminal environments

Version info:

wfuzz --version: 2.4
python3 --version: Python 3.7.3

Details

wfuzz doesn't work when environment is non-terminal or terminal emulator is detached.
I use SSH to run wfuzz on my server. It works normally when I run it directly but it doesn't work when I try to run it in the background then close the terminal.
I think it should check the environment before printing text.

To reproduce the issue:

ssh user@server
cd /tmp
nohup bash -c "sleep 10 && wfuzz -z file,/path/to/dict.txt -f result.txt -u https://example.com/FUZZ" &
exit

Wait 10 seconds...

ssh user@server
cd /tmp
cat nohup.out

Exception details will be saved to /tmp/nohup.out file.
Traceback of the exception is similar to the below one:

Traceback (most recent call last):
  File "/usr/local/bin/wfuzz", line 7, in <module>
    from wfuzz.wfuzz import main
  File "/usr/local/lib/python3.7/dist-packages/wfuzz/wfuzz.py", line 8, in <module>
    from .ui.console.mvc import Controller, KeyPress, View
  File "/usr/local/lib/python3.7/dist-packages/wfuzz/ui/console/mvc.py", line 143, in <module>
    class View:
  File "/usr/local/lib/python3.7/dist-packages/wfuzz/ui/console/mvc.py", line 144, in View
    widths = [10, 8, 6, 6, 9, getTerminalSize()[0] - 65]
  File "/usr/local/lib/python3.7/dist-packages/wfuzz/ui/console/output.py", line 80, in getTerminalSize
    tuple_xy = _getTerminalSize_linux()
  File "/usr/local/lib/python3.7/dist-packages/wfuzz/ui/console/output.py", line 154, in _getTerminalSize_linux
    return int(cr[1]), int(cr[0])
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

I think the problem is that function _getTerminalSize_linux() can't get size of the detached terminal emulator.

Hi @0xcoderman,

Have you tried using -o raw?

-o raw couldn't work.

This seems a bug, I will make a PR to fix it.

It should be fixed in 2.4.2
