fix: https://github.com/ArthurSonzogni/FTXUI/issues/296#issue-1092343846
When the list in Radiobox/Menu/Toggle is resized, clamp the |selected_| values so that it stays within bounds.
Clamping is executed in Render() and in OnEvent()

1. the default window size should be 80x24 rather than 80x25 in VT100.
2. the ioctl return value result should be checked. Some operating systems don't support TIOCGWINSZ this command.
Use std::string by default for the implementation of FTXUI's input
component.
Along the way:
- Give a correct implementation for fullwidth characters.
- Add tests
- Modify the way the cursor is drawn.
This implement the flexbox elements, following the HTML one.
Built from them, there is also the following elements:
- `paragraph`
- `paragraphAlignLeft`
- `paragraphAlignRight`
- `paragraphAlignCenter`
- `paragraphAlignJustify`
This is a breaking change.
In case of embedded systems, the terminal size may not
always be detectable (e.g. in case of serial output).
Allow application to set up the default size in case
autodetection fails. On platform such as Emscripten,
there is only "fallback" size.

Msvc defined its own (lowercase) macros for min/max. Because of this, the std::min and std::max functions need to be explicitly included or otherwise are not availible.
In the msvc 2019 compiler this issue seems fixed. However, on msvc 2017 not including <algorithm> causes compilation errors. Adding the include is a simple fix that does not hurt the other platforms and enables compilation on msvc 2017.
This can happen for example in embedded linux, in case
the application is started via serial terminal.

Dom
- `vscroll_indicator`. Show a scrollback indicator on the right.
Component
- `Maybe`: Display an component conditionnally based on a boolean.
- `Dropdown`: A dropdown select list.

- Password is now taking a ref, allowing a shared state to be used by
multiple passwords.
- Password cursor position is now optional. It will be used only when
set to something different from -1.
Screen::ApplyShader accounted for 60% of the computation. This patch
optimize it.
Performance on a 80x80 frame improved from 1400 draw/s to 7000 draw/s.
|hbox| and |vbox| are similar. They are just the same component, but
drawing in a different direction.
This patchs factorize the layout logic. Goal is to reduce code size and
reuse it for the |gridbox| dom element.
Bug: https://github.com/ArthurSonzogni/FTXUI/issues/114
In the past, FTXUI switched from std::string to std::wstring to support
fullwidth characters. The reasons was that fullwidth characters can be
stored inside a single wchar_t.
Then FTXUI added support for combining characters. A single glygh
doesn't even fit a wchar_t. Instead, a glyph can be arbitrary large.
The usage of wstring doesn't really fit the new model and have several
drawbacks:
1. It doesn't simplify the implementation of FTXUI, because of combining
characters.
2. It reduces drawing performance by 2x.
3. It increase Screen's memory allocation by 2x.
This patch converts FTXUI to use std::string internally. It now exposes
std::string based API. The std::wstring API remains, but is now
deprecated.
Tests and examples haven't been update to show the breakage is limited.
They will be updated in a second set of patches.
