Takes o3-button and refactors to work in an o2 world. Slightly
odd use of Sass/CSS Custom Properties, with Sass conditionals
used to output duplicate CSS Custom Properties which override
each other in the same declaration. This was the safest way
to reuse o3 styles by effectively replacing class names for
Sass if statements. It's also more readable and simple than o2
Sass. Despite duplicating some properties, CSS output and
performance will be improved by moving away from the Origami
Image Service for coloured icons.

Currently supports:
- Types
- Themes
- Sizes
- Icons
- Icons only

Does not yet support:
- Custom theme maps

Will not support:
- Outputting CSS granularly. There are not many buttons left in
o2 components, and bundle size is reduced overall as noted above.

Other things of note:
- `o-private-foundation-get` allows other o2 components to grab tokens directly.
- Added Metric2 variable font
