v0.4.0

Major changes

• Plugin now saves the detected autohighlight back onto the node so it doesn't have to "auto" highlight on every pass
  • sets to the node's params attribute by default
  • can be customized by passing a languageSetter function to the plugin
  • currently only works when the plugin is used within an EditorView (should satisfy the vast majority of users)

Breaking changes

• move preRenderer and postRenderer params to an options object param
• bump peerDependencies
