Add tmux-wormhole to the list of tcell-dependent apps

I published this yesterday on github. It's a tmux plugin that scrapes
the active tmux pane for a magic wormhole code, then downloads and
optionally opens the file tied to the code. I wrote this to make it
easier to get pcaps from termshark into Wireshark. This plugin uses
gowid which itself depends wholly on tcell to manipulate the
terminal. Link: https://github.com/gcla/tmux-wormhole
