[FFmpeg-cvslog] Add options for spatial layers.

[Thierry Foucu]

ffmpeg | branch: master | Thierry Foucu <tfoucu at gmail.com> | Wed Nov 27 16:25:33 2019 -0800| [eaf566ce0b9fd33120cc564bc7cd6986de3ca724] | committer: James Almer

Add options for spatial layers.

Disable by default to output all the layers, to match libaomdec wrapper.
Add option to select the operating point for the spatial layers.
Update the documentation with the new options.
