HQ core harmonization issue: peak_avrg_ratio_fx() in LR-HQ
In the LR-HQ encoder function `hq_lr_enc_fx()`, there is called a classification function `peak_avrg_ratio()`. Its first parameter is `total_brate`. In FLP, it looks as follows:
```
hqswb_clas = peak_avrg_ratio( st->total_brate, ... );
```
However, in BASOP, it is currently called
```
#ifdef HARM_HQ_CORE_KEEP_BE
hqswb_clas_fx = peak_avrg_ratio_fx( HQ_BWE_CROSSOVER_BRATE, ...s ); /* Q0 */
#else
hqswb_clas_fx = peak_avrg_ratio_fx( st_fx->total_brate, ... ); /* Q0 */
#endif
```
to keep the EVS BE.
The BASOP code thus does not follow the FLP, and it might be an EVS bug.
