Any chance you could add support for OpenBSD?

Hello, There are a number of things that could be done for this to work in OpenBSD. #!/usr/bin/env bash instead of #!/bin/bash

stty -F isn't a flag on stty on OpenBSD getopts --long and -n are not flags on OpenBSD.

FYI lsix works fine on OpenBSD once changing to env as above.
