Add support for level targetting

Enable the encoder to encode to the given target level.
Use existing encoder config to control the average bitrate, number of
tiles, and minimum compression ratio. Limit the bits spent on keyframes
and alt-ref frames to prevent bitrate spikes, which may cause the
decoder model to fail.
