Bug description

In the ParamMC reconfiguration function the hoa encoder needed for binaural rendering with head rotation is set to zero at the very beginning (copy/paste from the open function), leading to a missing hoa encoder after a switch from one ParamMC bit rate to some other.

Ways to reproduce

Hard to reproduce with one of the default rs files, since more things are broken there. Can be reproduced with this hand crafted rs file: pmc_rs.bin

.\IVAS_cod.exe -mc 5_1 .\pmc_rs.bin 48 .\scripts\testv\stv51MC48c.wav test.192
.\IVAS_dec.exe -t .\scripts\testv\headrot.csv BINAURAL 48 test.192 test.wav
