This fixes decoding of certain 7.1 DTS-HD HRA files, as well as matches the spec better.
Table 6-22 in the DTS spec labels the two channels "Left/Right surround on side", and not rear.

dca: set AVCodecContext frame_size for DTS audio
...
Set the frame size when decoding DTS audio.
This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.
