Add --freeze-right=N option to keep the rightmost N fields visible

Test:
  go run main.go --query "$(seq 100)" --info inline --border < <(sleep 60)
  go run main.go --query "$(seq 100)" --info inline --info-command 'echo hello' --border < <(sleep 60)

+- Added `--freeze-left=N` option to keep the leftmost N columns visible.
+  ```sh
+  # Keeps the file name column fixed and always visible
+  git grep --line-number --color=always -- '' |
+      fzf --ansi --delimiter : --freeze-left 1
+
+  # Used with --keep-right
+  git grep --line-number --color=always -- '' |
+      fzf --ansi --delimiter : --freeze-left 1 --keep-right
+  ```
+- Also added `--freeze-right=N` option to keep the rightmost N columns visible.
+  ```sh
+  fd | fzf --freeze-right 1 --delimiter /
+  fd | fzf --freeze-left 1 --freeze-right 1 --delimiter /

+
+0.66.1
+------
+- Bug fixes
+    - Fixed a bug preventing 'ctrl-h' from being bound to an action (#4556)
+    - Fixed `--no-color` / `NO_COLOR` theme (#4561)
