Florian Dehau 5a590bca74 chore: enable clippy on all targets and all features 
- Remove deny warnings in lib.rs. This allows easier iteration when developing
new features. The warnings will make the CI fails anyway on the clippy CI
stage.
- Run clippy on all targets (including tests and examples) and all features.
- Fail CI on clippy warnings.

Florian Dehau 584e1b0500 refactor(widgets/canvas): allow canvas to render with a simple dot character instead of braille patterns 
This change allows developers to gracefully degrade the output if the targeted
terminal does not support the full range of unicode symbols.

Florian Dehau 140db9b2e2 refactor(canvas): update shape drawing strategy 
* Update the `Shape` trait. Instead of returning an iterator of point, all
shapes are now aware of the surface they will be drawn to through a `Painter`.
In order to draw themselves, they paint points of the "braille grid".
* Rewrite how lines are drawn using a common line drawing algorithm (Bresenham).

Florian Dehau 6cb57f5d2a feat: add stateful widgets 
Most widgets can be drawn directly based on the input parameters. However, some
features may require some kind of associated state to be implemented.

For example, the `List` widget can highlight the item currently selected. This
can be translated in an offset, which is the number of elements to skip in
order to have the selected item within the viewport currently allocated to this
widget. The widget can therefore only provide the following behavior: whenever
the selected item is out of the viewport scroll to a predefined position (make
the selected item the last viewable item or the one in the middle).
Nonetheless, if the widget has access to the last computed offset then it can
implement a natural scrolling experience where the last offset is reused until
the selected item is out of the viewport.

To allow such behavior within the widgets, this commit introduces the following
changes:
- Add a `StatefulWidget` trait with an associated `State` type. Widgets that
can take advantage of having a "memory" between two draw calls needs to
implement this trait.
- Add a `render_stateful_widget` method on `Frame` where the associated
state is given as a parameter.

The chosen approach is thus to let the developers manage their widgets' states
themselves as they are already responsible for the lifecycle of the wigets
(given that the crate exposes an immediate mode api).

The following changes were also introduced:

- `Widget::render` has been deleted. Developers should use `Frame::render_widget`
instead.
- `Widget::background` has been deleted. Developers should use `Buffer::set_background`
instead.
- `SelectableList` has been deleted. Developers can directly use `List` where
`SelectableList` features have been back-ported.

Jeffas 94877f4e7e Use constraints for table column widths 
This allows table column widths to be adapted more and scale with the
UI.

The constraints are solved using the Cassowary solver. An added
constraint for fitting them all in the width is added.

Florian Dehau 3747ddbefb feat(backend): Refactor crossterm backend 
* Remove compilation warnings
* Fix rendering artifacts in the crossterm demo. In particular, the bold modifier
was leaking on most of the terminal screen because the old logic was not
properly unsetting the bold modifier after use (took inspiration of the termion
backend implementation)
