hDirAC handle in MASA

Using the code-base SHA-1: 30b12f8d from September 9, 2022, there was observed that the handle hDirAC is used only partially (8% decoder).

• ivas_dirac_dec_con 231 m:sizeof( DIRAC_DEC_DATA ) - 8% 1x2241 2241

hDirAC = (DIRAC_DEC_HANDLE) count_malloc( sizeof( DIRAC_DEC_DATA ) )

Can it be lowered?
