Bug description

While parsing directivity parameters in a render_config file that contains several directivity patterns, the directivity pattern ids associated with each directivity pattern are not stored in the correct index. When the -dpid command-line option is used to specify the id(s) used to set the directivity for each object, the id(s) are not found.

Ways to reproduce

Running

IVAS_cod.exe -ISM 1 ISM1met.csv 48000 48 ism1.wav bit
IVAS_dec.exe -render_config config_directivity_patterns2.cfg  -DPID 1 BINAURAL_ROOM_REVERB 48 bit out.wav

Results in decoder output
