Implement Commandline-Option for Binaural Audio

As discussed in https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/wikis/Meetings/Reports/2023-05-09-12-E-Meeting/2023-05-09-12-E-Meeting-Agenda/Design-Constraints:

A commandline option for Binaural Audio (Encoder-side) is required, to be on the safe side wrt Design Constraints. In addition, signaling in the bitstream (regular stereo <-> binaural audio) would allow for a differentiation on rendering-side.
