Tried out image preview in tmux using kitty

[jackielii]

Today I tried out lf with:

kitty: nightly at kovidgoyal/kitty@31d8a98
tmux: 3.3a

It looks like this

A couple of issues still exists:

1. When switching to the image, the font changes (from 22s in the clip). I suspect this is an issue in kitty nightly.
   Somehow kitty nightly increases the font weight by 1. I.e. I use to use Fira Code Medium, but now I have to use Fira Code Regular to have the same effect
2. "loading..." text is not cleared and overlays on top of the image
3. The preview doesn't clear properly. The info is ok through. (See my dotfiles1 for the mapping)
4. I had to decrease the size by one in order to have the image fit the screen. Maybe it's because lf didn't take the border into account? Also see 1 for details
