webm video presets: migrate from VP8 to VP9 for smaller ZIMs #170

Closed benoit74 closed 3 months ago

Fix #79

WebmLow and WebmHigh presets are migrated to use VP9 instead of VP8.

Presets are also enhanced to maximize video quality all while minimizing final file size. A compromise with encoding duration (which is known to be significantly higher with VP9 compared to VP8) is also taken into account (hence the -speed setting values, 0 is optimal but takes too long for minimal quality improvement given our computing power available)
