tui: patch crossterm for better color queries (#5935)

See
https://github.com/crossterm-rs/crossterm/compare/master...nornagon:crossterm:nornagon/color-query

This patches crossterm to add support for querying fg/bg color as part
of the crossterm event loop, which fixes some issues where this query
would fight with other input.

- dragging screenshots into the cli would sometimes paste half of the
pathname instead of being recognized as an image
