Draft: [Audio to Action] Video Generation

[prasoonvarshney]

Accompanying changes for home-robot PR 409

Rebases ovmm_videos_with_interpolation onto ovmm, and a couple other video generation changes

Minor camera configuration changes and text overlays in video generation

@yvsriram I don't have edit access to this repository - can you create a new branch called eai_audio_action based on ovmm? I'd rather recreate this PR to be from prasoonvarshney/habitat-lab:eai_audio_action onto facebookresearch/habitat-lab:eai_audio_action, instead of onto facebookresearch/habitat-lab:ovmm?

Done @prasoonvarshney - I created the branch
