Prefer std::string over std::wstring. (#179)
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.

Extract common struct Dimensions from Terminal (#171)
- 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).

Remove explicit default destructors (#157)
From CppCoreGuidelines:

Rule of Zero: C.20: If you can avoid defining default operations, do.
C.52: Use inheriting constructors to import constructors into a derived class that does not need further explicit initialization.
DRY forward and using declarations.
Miscellaneous:

Fix format.sh to output examples with normalised paths in sorted order.

Support combining characters. (#121)
Modify the ftxui::Pixel. Instead of storing a wchar, store a
std::wstring. Now a single pixel can store multiple codepoints.
If a codepoint is of size <=0, it will be appended to the previous
pixel.

Only ftxui::text() is supported. ftxui::vtext support still needs to be
added.

This causes the following CPU and memory regression:
- Memory: Pixel size increases by 200% (16 byte => 48byte).
- CPU:    Draw/Second decrease by 62.5% (16k draw/s => 6k draw/s on 80x80)

Both regressions are acceptable. There are still two orders of magnitude
(100x) before the levels where performance/memory concerns begins.

6f87740801 Compatify the Screen memory.
Instead of storing all the booleans with 5 bytes, use a bit field.
The size of a Pixel has been reduced by 25%, from 20 byte to 15 bytes.

e1a71d5b9f Use shared_ptr instead of unique_ptr for elements.
This allow users to pass it into initializer list. Then clang-format
will produce 'acceptable' indentations.

86c3b60a6f Move the cursor to the input location.
Most CJK users use IME (input method) to type CJK characters. They need
the cursor to be at the correct location, not in the bottom right
corner.

This CL does:
 * Move the cursor the focus() element.
 * Hide the cursor (and show it at exit)
 * Intercept SIGINT to guarantee proper cleanup all the time.

This should fix the second issue mentionned on:
