Run wsget cli non-interactively (w/o `/dev/tty`)

[srkaj]

Hi! Thanks for making wsget!

Is it possible to run wsget non-interactively, without access to /dev/tty? I'm trying to use it for testing a websocket server in CI (github actions), but it keeps failing with this message:

  25lUse Enter to input request and send it, Ctrl+C to exit
  25hError: keyboard input failed: open /dev/tty: no such device or address

I have tried running both with a --request parameter and with a script.yaml looking like this:

- send {"my":"payload"}
- wait 10
- exit

If it is not currently possible, could a CLI argument be added to turn of the interactive parts? Or maybe disable them by default when a --request argument is given?

I have looked through this github repo for any (undocumented) way to turn it off, but haven't found it (though I'm no expert in the golang ecosystem). What I did find is some tests in wsget that deliberately ignores this error, so I guess they don't really test anything when running in github CI. So I guess the feature I'm requesting would be useful there too.
