v3.5.3

• Improved the usage of the ratio config option; it now works as expected and for all video types. The default has not changed, it is to dynamically, where possible (except YouTube where 16:9 is used) determine the ratio from the media source so this is not a breaking change.
• Added new ratio getter and setter
• Fix: Properly clear all timeouts on destroy
• Fix: Allow absolute paths in preview thumbnails
• Improvement: Allow optional hours and ms in VTT parser in preview thumbnails
