[non-io] Resolve "RTPDUMP is not RTPDUMP"

Stefan Doehlarequested to merge
1438-rtpdump-is-not-rtpdump into main

Reason why this change is needed

  • Alignment of RTPDUMP implementation to rtptools and what is implemented on float

Description of the change

  • ivas_rtp_file now uses the existing rtpdump implementation
  • various fixes in rtpdump code

Affected operating points

  • all VoIP bitstreams as the format changes
  • In minimum, there should be a status for bitstream compatibility and output bit exactness
  • For bitstream compatibility, the following levels are helpful for describing encoder
    1. Produced bitstream is BE compared to previous state.
    2. Produced bitstream is non-BE but it is fully backwards compatible for decoding. Decoded output may differ.
    3. Produced bitstream is non-BC. Old decoder cannot decode the produced bitstream correctly.
  • For output difference, use BE or non-BE. Additionally, amount of difference can be presented.

Closes #1438 (closed)
