sixel-bytes, optional serde, Send+Sync, rustix::termios icotl, fixes

* `sixel-bytes` encodes to `String` instead of file.
* `serde` for `BackendType` for e.g. user configs.
* `Send + Sync` for threads/tokio.
* `rustix::termios` to get window/font size until ratatui/crossterm get `window_size()`:
  [`ratatui::Backend::window_size()`](ratatui-org/ratatui#276) needs [`crossterm::terminal::window_size()`](crossterm-rs/crossterm#790).

 Render images with supported graphics protocols in the terminal with ratatui.
 While this generally might seem *contra natura* and something fragile, it can be worthwhile in
 some applications.

 For this resizing it is necessary to query the terminal font size in width/height.

 The [`FixedImage`] widget does not react to area resizes other than not overdrawing. Note that
 some image protocols or their implementations might not behave correctly in this aspect and
 overdraw or flicker outside of the image area.

 Each widget is backed by a "backend" implementation of a given image protocol.
 
+## Backends

 Currently supported backends/protocols:
 
-## Halfblocks
+### Halfblocks
 Uses the unicode character `▀` combined with foreground and background color. Assumes that the
 font aspect ratio is roughly 1:2. Should work in all terminals.
-## Sixel

 Experimental: uses temporary files.
 Uses [`sixel-rs`] to draw image pixels, if the terminal [supports] the [Sixel] protocol.
