Add option to change cursor shape on exit of ScreenInteractive loop

[dangooddd]

Currently there is no option to set cursor_reset_shape_ on ScreenInteractive class. Because of that, cursor is always block and blinks (cursor shape is always 1).

This PR adds SetCursorReset method as option.

Will close #904

Thanks!

I don't think it works. FTXUI request the terminal to reflect what is the current cursor here (1), save it here (2), and restores it here (3)

I believe the value set by this new API would be overriden by (2), doesn't it?

Why do you need this API? Are you suggesting the current way of requesting/restoring the cursor value doesn't work?

Sorry, i just had not seen https://github.com/ArthurSonzogni/FTXUI/blob/main/src/ftxui/component/screen_interactive.cpp#L604. Indeed, restoring cursor this way will be better than set this manually with New API.

Problem is that in my case ftxui always sets blinking cursor no matter what i do. I will try to debug this and describe the problem latter. Also in #904 I guess problem exactly like i have
