Crashes over SSH (both in and out of tmux)

lookatme.log
Describe the bug
Loading the second slide in the examples/tour.md document causes lookatme to crash with the following error:

Error rendering slide 2: 'DequeCommandTransmitter' object has no attribute 'transmitter'
See /tmp/lookatme.log for traceback
Aborted!

I get that it's probably really weird to be using this over SSH, but my work laptop's display output doesn't work with my KVM, so I tend to just SSH into it from my desktop. I've attached a log after running lookatme --debug tour.md

To Reproduce

1. Connect to a remote host over SSH
2. lookatme tour.md

Expected behavior

Either the slideshow should run (which given the Ueberzug and Terminal extensions is probably unrealistic) , or should gracefully handle errors caused by being run over SSH.

Environment (please complete the following information):

• OS: Arch Linux (btw)
• Lookatme Version: 2.3.2 installed via pip

I see this error also locally, if I use the extension "image_ueberzug".
Environment: Mac M1 , MacOS 12.6, pyhton 3.10.8, with homebrew 3.6.6

I think this could be described as lookatme needing better error handling in general when dealing with extensions. The terminal extension shouldn't be a problem, but I could definitely see the image_ueberzug causing problems.

Same problem, I got this presentation that I'm supposed to do tomorrow... Weird how on my desktop (Void Linux) this still works but on my Arch laptop it doesn't.

[d0c-s4vage]

@tommitah are you using any extensions, or is it crashing with stock/plain lookatme?

[tommitah]

@d0c-s4vage My bad, was supposed to mention the image extension. Same setup as OP, except local.

It works without the extension, guess my presentation will be a tad more boring this time.

[d0c-s4vage]

Ah, yeah. The image extension uses ueberzug, which uses X11 to render/hide the image onto the the section of the screen so that it lines up with the terminal. Since it is X11, there's probably some way to get it working with X11 forwarding over SSH, but I haven't tried that yet.
