Space reserving tweaks for huge video resolutions 

* improve space reserving, allows write better 4K/8K video data
* do not use cache dirs in the muxers, Android can force close NewPipe if the device is running out of storage. Is a aggressive cache cleaning >:/
* (for devs) webm & mkv are the same thing
* calculate the final file size inside of the mission, instead getting from the UI
* simplify ps algorithms constructors
* [missing old commit message] simplify the loading of pending downloads
