China list cleanup: BesTV

* BesTV / BesTV超级体育6-HD / BesTV超级体育FHD
  * Removed, only the same ad playing over and over.
* BesTV 4K
  * Added the Chinese name 百视通.
  * Added logo.
  * Added Mandarin Chinese language.
* BesTV超级体育 / BesTV超级体育3-HD
  * Added Chinese name 百视通
  * Using the same name, it's the same content in the same resolution.
  * Added "(Backup)" to one of the channels. It's actually probably the same stream but it's hard to say with a different URL.
  * Added Mandarin Chinese language.
  * Added logo.
* BesTV超级体育5-HD
  * Not the sports channel it says it is. Not sure if it is even a channel, it says it's is educational stream broadcasting classes for grades 1-6 Monday-Friday. I changed name and category accordingly.
  * Added logo.
