Mismatch of declaration and definition of computeIntensityVector_ana and computeReferencePower_ana

The input array size in the declarations of functions computeIntensityVector_ana() and computeReferencePower_ana() in lib_rend/ivas_prot_rend.h differ from the one in the definitions in lib_rend/ivas_omasa_ana.c.

Declaration:

float Cldfb_RealBuffer[DIRAC_MAX_ANA_CHANS][CLDFB_NO_CHANNELS_MAX], /* i  : Real part of input signal       */
float Cldfb_ImagBuffer[DIRAC_MAX_ANA_CHANS][CLDFB_NO_CHANNELS_MAX], /* i  : Imag part of input signal       */

Definition:

float Cldfb_RealBuffer[FOA_CHANNELS][CLDFB_NO_CHANNELS_MAX], /* i  : Real part of input signal       */
float Cldfb_ImagBuffer[FOA_CHANNELS][CLDFB_NO_CHANNELS_MAX], /* i  : Imag part of input signal       */

The version from the definition is the correct one and the prototype should be aligned with this.
