Feature Request: Add option to show only widget passed through commandline argument

[xypnox]

Sometimes, The usecase is such that we only need to monitor one thing. For example, We may need to only see the network widget or memory widget.

Hence, Add a command-line option that takes the name of the widget and displays only that widget.

This will be helpful in case of tiled terminals with small terminal area.

A sample Command line interface could look like:

gotop --widget=network

gotop -w network

This feature would be very usefull, if possible please allow multiple like -w=CPU,Memory,Network,Processes or similar.
This way it would be able to hide the Temperature-boxes for example, which are usually empty on my VMs anyway.
