[Player] Reduce memory usage for long videos

[mikeyaworski]

Playing long audio such as https://www.youtube.com/watch?v=yIQd2Ya0Ziw will cause the bot to accumulate memory usage through the entire duration of the audio. Once the player is fully done with the audio resource, all of the memory will be freed up. But it's unnecessary for all of that memory to remain consumed while the video is playing since it's being streamed and rewinding is supported.
