opus-tools: Update to 0.2. Make audio output in opusdec work.

opus-tools 0.2

   Sep 18, 2018

   In this release the Opus decoder opusdec has been converted to use the
   opusfile library, and the Opus encoder opusenc has been converted to
   use the libopusenc library. These libraries make it easy to robustly
   read and write Ogg Opus audio files, and enable some new features.

   opusdec enhancements include:
     * Read directly from http or https sources
     * New option --force-stereo will force stereo output
     * Improved support for chained input files with differing sample rate
       or channel count
     * A summary is displayed for METADATA_BLOCK_PICTURE tags rather than
       displaying the base64-encoded data

   opusenc enhancements include:
     * Delayed decision support allows the encoder to look ahead up to two
       seconds in order to improve encoding decisions
     * The options --music and --speech can be used to tune low bitrate
       audio for music or speech, overriding automatic detection
     * The option --no-phase-inv disables the use of phase inversion for
       intensity stereo, which can be useful for streams that are likely
       to be downmixed to mono after decoding
     * New --tracknumber shortcut for setting tracknumber metadata

   Additionally:
     * The opusinfo utility can display the demixing matrix from Ogg Opus
       files using ambisonics channel mapping family 3
     * The experimental opusrtp tool supports new options to specify RTP
       payload type, Ogg Opus output file, original sample rate, and
       number of channels, and supports improved transmit timing,
       arbitrary network devices, and IPv6
     * Numerous bug fixes are also included
