rinetd package request

Please may a rinetd package be added. rinetd is used to redirect connections from one address port combination to another. rinetd is included in Debian and Ubuntu.

rinetd is used in Docker containers like Docker WireGuard Tunnel to create a tunnel between two Docker containers running on separate networks.

xiaozhuai has ran rinetd on Alpine.

I believe a package for rinetd would expand the tool set that the Alpine community has available for creating useful and lightweight Docker images.
