Bug description

When rendering in CLDFB domain to BINAURAL_ROOM_REVERB output format coloration appears. This coloration also appears if reverb generation functions are disabled.

Ways to reproduce

There are two ways to reproduce this issue: by disabling the reverb functions in the code (see branch), and by providing dry custom reverb configuration (i.e., with minimum T60 and zero DSR values). The coloration effect is different in these reproduction scenarios.

Waveforms and spectrograms are illustrated below:

1. BINAURAL output format
2. BINAURAL_ROOM_REVERB output format with reverb functions disabled in the code
3. BINAURAL_ROOM_REVERB output format with dry reverb configuration rend_config_dry.cfg
