Typography.js Files

Two breaking changes in interest of simplifying the UI. - baseLineHeight takes the css unitless number now instead of a px value. This is what most people use for line-height so made sense to make the switch. PX values still work so this isn't technically a breaking change but you're encouraged to switch things over. - modularScales is now just scale. I decided to consolidate various responsive typography concerns into a coming breakpoints option. Instead of passing an array of options to modularScales do something like:

:::javascript
{
  scale: 2
}
