Add Server List Selection Feature

[lgjint]

I want to select a server for testing, but it currently requires two steps: first running speedtest-go --list to generate the server list, and then specifying the server with speedtest-go --server.

I would like to request a feature that displays a list of available servers and allows users to select a server using the up and down arrow keys for testing. This would greatly enhance the user experience by simplifying the server selection process. Thank you!

If an interactive command is added to speedtest-go, it will break and cause many third-party script calls to encounter exceptions. I think the status quo should be maintained. Just like the official speedtest, it is no interaction.
