[Feature Request] Whitelist supports CIDR

[MidwatchCowboy]

Is your feature request related to a problem? Please describe.
I'm not sure if I'd call it a problem since so few users are likely to be in my situation. The plugin kills shell/console connections in the browser (such as for proxmox). This makes it unusable for me unfortunately.

Describe the solution you'd like
I would like for the whitelist to support IP addresses and CIDR notation.

Describe alternatives you've considered
I'm not savvy enough on plugin development to offer any technical insight in to what causes this issue.

Additional context
Thank you for the plugin. I completely understand this is likely a low priority.

I second this, this would be extremely helpful. For a few weeks I couldn't connect to my proxmox shells and after pulling my hair our for a while I realized it was this extension blocking port 8008 and thus blocking my connection to the shells. I almost completely reinstalled proxmox but held off because I could connect through my Ipad and that made me realize it was a issue from my PC and not the server. TLDR I have to disable this extension every time I have to do something in proxmox.
