Feature Request: Support Blinking Cursor Indicator

[CodeWenjiu]

Would this feature be feasible?

You mean like:
https://docs.rs/crossterm/0.28.1/crossterm/cursor/enum.SetCursorStyle.html
https://docs.rs/termwiz/latest/termwiz/surface/enum.CursorShape.html
, right ?
It depends on when you want to change the cursor (because currently you cannot perform multiple actions after one keystroke, see #306)
And we must check if some bookkeeping is needed to restore its initial state.
