- Platform: all
### 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](/uploads/24d1f1bcc5074296fad5d62909030d9f/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
```
