Use sixels on Windows when available

[johnd0e]

Latest Windows Terminal supports sixels output, and it works when I specify -f sixels option explicitly

Perhaps it would be better to use it by default.

Yes - at least long term, that's how I'd like it. But we can't distinguish between older Windows Terminal and the newer versions with sixel support, so we should probably wait until more users have upgraded.

Do people generally keep Windows Terminal up to date?

@hpjansson, the yazi developer seems to query the terminal for sixels support like so: (microsoft/terminal#17809 (comment)). I don't know if this is feasible for chafa though.
Also, the current stable release doesn't support sixels, however the current preview release does.

It is, I just have to get over my API anxiety and implement an async terminal handler.

You could use the "Send Device Attributes" escape sequence to detect sixel support.
For Reference see this document
Edit: I just noticed this was basically already proposed, but you can still use the link I provided as a reference, since its the exact same thing

Yep. Similar discussion in #191. Thanks.
