Floating-point leftovers: lib_com/ivas_dirac_com_fx.c, ivas_dirac_config_fx.c
# Bug description
In `ivas_dirac_config_fx()` there is some floating-point code left (lines 221ff.):
```
IF( EQ_32( ivas_format, SBA_FORMAT ) || EQ_32( ivas_format, SBA_ISM_FORMAT ) )
{
// 100861_dirac_dec
ivas_dirac_config_bands_fx( band_grouping, IVAS_MAX_NUM_BANDS, (Word16) ( Fs * INV_CLDFB_BANDWIDTH + 0.5f ), dirac_to_spar_md_bands, hQMetaData->useLowerBandRes, hConfig->enc_param_start_band, hFbMdft, 1 );
}
ELSE
{
ivas_dirac_config_bands_fx( band_grouping, hConfig->nbands, (Word16) ( Fs * INV_CLDFB_BANDWIDTH + 0.5f ), NULL, 0, 0, hFbMdft, 1 );
}
```
