[x] save synthesis update in core dec fix
[x] Moving intermediate FTF conversions outside wb_tbe_dec, swb_CNG_dec_ivas_fx, swb_bwe_dec
[x] Conversion of ivas_td_binaural_renderer_sf subfunctions
[x] Integerate and convert subfunctions of ivas_mc_dec_config
[x] ISM init cleanup
[x] Fix for issue #717
[x] Removes redundant flags/variables from td_cng_dec_structure
