Element gaugeLeft(float ratio);
Element gaugeRight(float ratio);
Element gaugeUp(float ratio);
Element gaugeDown(float ratio);
Element gaugeDirection(float ratio, GaugeDirection);
```
- Add the `automerge` decorator. This makes separator characters to be merged
  with others nearby.
- Fix the `Table` rendering function, to allow automerging characters.

### Features:

#### Screen
- Add the `automerge` to the Pixel bit field. This now controls which pixels are
  automatically merged.

#### DOM:
- Add the `Canvas` class and `ElementFrom('canvas')` function. Together users of
  the library can draw using braille and block characters.
- Support `flexbox` dom elements. This is build symmetrically to the HTML one.
  All the following attributes are supported: direction, wrap, justify-content,
  align-items, align-content, gap
- Add the dom elements helper based on `flexbox`:
  - `paragraph`
  - `paragraphAlignLeft`
  - `paragraphAlignCenter`
  - `paragraphAlignRight`
  - `paragraphAlignJustify`
- Add the helper elements based on `flexbox`: `hflow()`, `vflow()`.
- Add: `focusPositionRelative` and `focusPosition`
- Add `Table` constructor from 2D vector of Element, instead of string.

#### Component 
- Add the `collapsible` component.
- Add the `ScreenInteractive::WithRestoredIO`. This decorates a callback. This
  runs it with the terminal hooks temporarilly uninstalled. This is useful if
  you want to execute command using directly stdin/stdout/sterr.
