Fix point hrtf binary file format

Currently float data tables for the different binaural renderers are stored as float values in the hrtf binary file. To make the hrtf binary file compatible with the Fix point version of the IVAS codec, integer values related to the Fix point version of the IVAS codec shall be stored instead. When loading hrtf binary file to the floating point version of the IVAS codec, integer values corresponding to float values shall be converted to float.
