Add support for playit.gg

Describe your feature request
Provide support for playit.gg and allow Repls to access the service.
What problem(s) would this feature solve?
Playit is a reverse proxy service that allows raw TCP servers and UDP services to be exposed to the internet. It is simiar to ngrok, but playit provides a free domain that doesn’t change and has support for UDP.
Explain what you were trying to do when you came across the problem leading to this feature request
I was trying to create a playit tunnel to expose a Minecraft server for outside access, but the tunnel failed to establish a connection to playit’s servers, and I believe this is due to UDP packets being dropped by a firewall, preventing communication to and from the service.
