Mediabunny HEVC Decoding

HEVC files read and decoded by Mediabunny, with hevc.js as its decoder where WebCodecs has none

Force hevc.js (bypass native HEVC detection, reloads the page)

Decode in a Web Worker (on the page's thread otherwise, reloads the page)

Decode as fast as possible (frames are shown at their timestamps otherwise)
