## Description
- Add fluid root unit
- Add fluid tokens for typography, spacing and sizing
- Add docs about Theme
- Typography now works by creating a class at the provider level
- Update styled component version. Add PickRename interface to work with
[transient
props](https://styled-components.com/docs/api#transient-props)
- Remove the direct use of rootUnit and replace it with sizing tokens
- Get rid of some unit test because new version of styled components
doesn't work with Jest. Fortunately, we have visual tests.

## Description
**Typography**
- Move typography to the provider.
- Add context for the theme provider
- Move `fontFaces` styles to the provider
**Tooltip**
- Add `isRounded` check for the tooltip (shift for the arrow)
- Fix the position of the arrow in the tooltip
**Tokens**
Move `rootUnit` from `sizing` since this is a common value and is used
not only for sizing. We will do the sizing iteration separately, if
necessary.
**Theming package**
Theming package refactoring. So now we have 4 folders (color, theme,
token, and typography) with related files
