notes.md

• Takes a LivePhoto and will create a an LivePhotoView and calls toImage on it ten times, measuring the overall time taken and the time taken for each loop
• On average for 10 loops it will taken around 9-10 seconds with each loop taking around 900-1000ms. It's possible this could be reduced by parallelising the conversion
• While the images are being processed the UI is blocked, I'm uncertain whether it's possible to perform this an not block the UI
