* Updated how tags are rendered to allow for custom styling via space-styles
* Wrapped the existing span for a tag with an anchor element <a> to
improve ux for screen readers
* Added data-tag-name attribute to tags so that given a tag `#my-tag` it
will have the attribute `data-tag-name="my-tag"` added to the new `<a>`
element wrapper allowing for end users to target tags for styling with a
css selector such as `.sb-hashtag[data-tag-name="my-tag"]{...}`
* Updated Docs
