[FEATURE] libsixel support?

[jedahan]

There are some feeds I follow that use images that are crucial to the understanding of the feed. I would love to be able to view these images without having to leave neix.

Describe the solution you'd like
DEC SIXEL is a simple pixel format that enables terminals to display high resolution graphics https://github.com/saitoha/libsixel . I'd love to see (optional, autodetected and opt-out) support for sixel escape codes.

Describe alternatives you've considered
Any way to externally run custom commands would kinda be a workaround but seems a little excessive.

Integrating libsixl is a pretty big task. Unfortunately I didn't have the time right now.

I added the help wanted label, so maybe there is one who will help out.
