dcp: Add case GET_PTS_DELAY in Control()
dcp: Add case GET_PTS_DELAY in Control()

Use the option --file-caching to set PTS_DELAY
Default caching value is 30s, okay for DCPs with 100Mb/s bitrate
For higher bitrates and high resolution values, file-caching shall
be reduced. Avoid fifo full problem in decoder.
