Improve SVG Performance (#841)

* Improve SVG Performance

This PR introduces three new classes:  `svgNode`, `pathNode`, and `lineNode`. SVG data is then loaded into the domTree exclusively via instances of these classes.

`innerHTML` is banished.

* Fix lint errors

* Fix \cancel typo

* Fix sqrt height

* Adjust min-lenght

Adjust some of the extensible arrows to get a min-length that matches glyph length of the long arrows in KaTeX Main font range from Unicode 27F5  to 27FC.

The accent arrows still get min-lengths that match the arrows in the Unicode 2100 range.

* regenerate screenshots after optimizing SVG code

* update DisplayStyle screenshot for Chrome

* update OverUnderset and Smash screenshots for Chrome as well

* Remove escapes from template strings

* Pick up review comments

* Fix lint errors

* Add comments
