v2.1.0 - the one that can pause videos when scrolled off screen

• Added an option to pause videos when they are scrolled off screen (#4)
• Updated the Vimeo player library from v2.10.0 to v2.12.2 (#2)
• Switched to view/model as view-only components are now deprecated
• Fixed a bug where, if you had both inline transcript and external transcript enabled, clicking the inline transcript button also changed the label on the external transcript button
• Fixed a copy-paste error that was preventing the transcript button label from being updated on transcript open/close
