Add network usage in `ps` command

[HKalbasi]

Basics

• I have done a basic search through the issue tracker to find similar or related issues.
• I have made myself familiar with the available features of Nushell for the particular area this enhancement request touches.

Related problem

I want to see the bandwidth used by the system, mostly to monitor progress and health check of huge downloads. I know nload in linux, but nothing in windows, it would be great if nushell gains this functionality.

Describe the solution you'd like

Add a column to sys net showing the bandwidth usage of each interface, or add a column to ps showing the bandwidth used by each process.

Describe alternatives you've considered

I know no nushell based alternative for this task. We can parse output of other programs, but I don't know any cross-platform tool for this job either.

Additional context and details

We use the sysinfo crate for this information. If it's provided it could be added pretty easily.

[HKalbasi]

It seems that crate has it for whole interface (https://docs.rs/sysinfo/latest/sysinfo/struct.NetworkData.html) but not for each process. It covers my use case, but I can also open an issue on that crate for having this data for each process as well.

[HKalbasi]

Looking more at this, it is somehow exposed as sent and received. So I can do something like this:

(1..) | each { let prev = sys net | where name == "wlp5s0" | ($in.0.sent + $in.0.recv); sleep 1sec; sys net | where name == "wlp5s0" | ($in.0.sent + $in.0.recv) - $prev }

I'm going to change the title to exposing this data in ps per process.
