[Rend Non-BE]Add fix NONBE_FIX_1337_MISSING_DIRECTIVITY_DISTATT_EXTREND

• Related issues: #1337 (closed)
• Requested reviewers: @demirkanik, @tamarapu

Reason why this change is needed

While preparing the 6-DoF rendering test, where the reference is prepared with IVAS_rend, we found that the external renderer does not apply the directivity and distance attenuation settings. This is critical for the characterization testing. The fix should be quite simple, though, just adding the call to the configuration in renderer.c.

Description of the change

Adds the necessary calls from decoder.c to renderer.c to apply the directivity and distance attenuation configuration.

Affected operating points

• External renderer with directivity and distance attenuation settings done via -render_config.
