Obj editing issue: negative energy estimation used for gaining

Overview

With some editing inputs and input files, the estimated totalTargetEneCh[ch] used for estimating the applied gains may exceed the estimated original channel energies in ivas_omasa_preProcessStereoTransportsForEditedObjects(). This causes further incorrect output gaining behavior (e.g., amplification with g<1 gain editing input).

Ways to reproduce

./IVAS_enc -ism_masa 4 2 testv/stvISM1.csv testv/stvISM2.csv testv/stvISM3.csv testv/stvISM4.csv testv/stv2MASA2TC48c.met 96000 48
testv/stvOMASA_4ISM_2MASA2TC48c.wav
bit

./IVAS_dec -obj_edit NULL BINAURAL 48 bit out.wav

Editing input can be enabled by modifying do_object_editing() function in apps/decoder.c to use following input:

editableParameters->ism_metadata[0].azimuth = -90;
editableParameters->ism_metadata[1].azimuth = -90;
editableParameters->ism_metadata[2].azimuth = -90;
editableParameters->ism_metadata[3].azimuth = -90;

editableParameters->ism_metadata[0].gain = 0.5;
editableParameters->ism_metadata[1].gain = 0.5;
editableParameters->ism_metadata[2].gain = 0.5;
editableParameters->ism_metadata[3].gain = 0.5;
editableParameters->gain_bed = 0.5;
