pwt ("port wait") is a commandline utility that blocks until a tcp socket, aka port becomes available. Designed to replace the bash sleep command in your CI/CD scripts, this process will exit with 0 once the socket connects, or -1 in the event of a timeout.

• -h -v flags for cli
• bumped to go 1.20
