Player v2.6.0

This new version of the npm player is focused around the bad network mode feature. The ABR algorithm works best on qualities of 800 kbit/s or more. For advanced use cases, one might want qualities with a lower bitrate. Therefore we added a bad network mode to the player. By default, these very low bitrate qualities are not selected by the ABR algorithm to ensure a optimal ABR experience. However, if the player detects that it really isn't possible to play the higher bitrate qualities it will select a very low bitrate quality. This is called entering bad network mode. If this happens, we can provide no guarantees that the ABR algorithm will be able to switch up in the future. But if it happens, the player exits bad network mode and will only choose the higher qualities again.

Also some bugfixes where made to prevent the player from sometimes stalling for a extended period on a quality switch.
