add support for windowing in select

[cylewitruk]

Offers a solution for #64 by allowing the user to specify a max window size -- works with filtering as well. See the select_window_size example.

An ultimate solution would probably use something like termsize and calculate based on the actual size of the viewport.

@cylewitruk It's better to move with the ultimate solution with automatic terminal size identification.

@fadeevab alright, will have a look at that then too. I still want the windowing function so I can control the display size of the list if I want to, but using terminal size as a default will be a huge improvement 👍

I think the termsize solution will simply set the window size to term height - header - [filter] - footer roughly, as a default anyway.

I'll probably expose some convenience function to get terminal size to the consumer as well, in-case they want to do their own window size caculation (could be embedded in a TUI or something).

@cylewitruk. Busy days. I hope I will review it soon.

@fadeevab no rush 😊

@cylewitruk

Thanks for the patch! :) I believe this part should be used in the multiselect as well, thus I would ask to move it into a separate structure, e.g. "TermSize", something like I did with filter.rs for filtering in the both selection lists.

TermSize::default()
TermSize::get_size() -> usize
TermSize::set_size(usize)

@fadeevab agreed, been a bit tight with time the last weeks but I'll get to this eventually 😄

@cylewitruk hello, no rush :) meanwhile, we managed to release few improvements to the multiprogress bar (insert and println)
