Please implement a configurable timeout

[x8-999-github]

Hello,

I have successfully used the python-vxi11 on a rigol MSO1104z over TCP.
See
https://github.com/x8-999-github/cw-projects-experiments/blob/master/visa/Scope_arm_and_capture.ipynb and

https://github.com/x8-999-github/cw-projects-experiments/blob/master/visa/VXI_MSO1104z.ipynb

The main problem was a timeout I was getting when connecting.
Is it possible to make the socket timeout configurable(I hardcoed it here)?

import socket

socket.setdefaulttimeout(5.0)

the code above helps me out 😆
