Makes it appease fbcode internal tests

* Add option to write audio to video file

Summary:
I was trying to use torchvision's `write_video` function and realized there was no option to add in the audio.

Thus, this diff contains the changes necessary such that this is possible. This is my first time trying to contribute to this project, so be as harsh as you need!

* torchscriptable functions for video io (#1653)

Summary:
Pull Request resolved: https://github.com/pytorch/vision/pull/1653



created new torchscriptable video io functions as part of the api: read_video_meta_data_from_memory and read_video_from_memory.

Updated the implementation of some of the internal functions to be torchscriptable.
