fix binaural output part in smoke test
There is a bug in the binaural output + -hrtf
option portion of the smoke test. That part should run all binaural-capable input modes with BINAURAL and BINAURAL_ROOM output using -hrtf
to pass an external HRTF file. Due to a scripting error, only all non-binaural modes were actually run. This MR fixes this bug.
