- Fix focus in flexbox. This required resetting the focus state at the
beginning of the ComputeRequirement(), because it can now run several
times.
This resolves:https://github.com/ArthurSonzogni/FTXUI/issues/399
- Add Box::Union.
- Add a preliminary implementation of forwarding selected_box from
within the flexbox.
Add decorator variants for decorator components
Add the "pipe" operator for components, similar to what was done for Elements.
We are able to put something like:
```
Button(...) | Maybe(&show_button)
```
Add decorators for:
- `Maybe`
- `CatchEvent`
- `Renderer`

ftxui::Ref<> is used for passing Options, for instance, MenuOption,
to the corresponding component which is supposed to hold a strong
reference of it. and we can observe the events sent to the component
by setting callback(s) in the option instance passed to the owner
component.
but the callback function is not always copyable, despite that it
might be moveable.
in this change,
* Make<>() is updated to use the perfect forwarding to avoid
enforcing its parameters to be copyable.
* Ref<> is also updated to take a rvalue reference, so we can
move away from the contructor parameter when creating an
instance of Ref<>() from it.

- Add support for SIGTSTP:

- Add support for task posting.
This allows folks to defer function execution, and execute it directly
below the main loop. The task are executed in a FIFO order.
Add the `automerge` attribute to the Pixel bit field. It controls
whether two pixels must be automerged. Defining this allows two
mergeable characters not to be merged.

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.

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.
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.

- Convert Dimension to namespace to allow defining Fit method from dom.
- Use Dimensions extracted from Terminal as replacement struct.
- Convert Terminal to namespace as it only defines static members.
- Remove dom references from screen library (circular dependency).
- Invoke DetachAllChildren from ~ComponentBase
- Define Focused using Active
- Compact TakeFocus loop code
- const-correctness for Parent, Active and Focused
