[CI] Make batch_comp_audio.py able to use the mld tool
scripts/batch_comp_audio.py
can be used to compare same-name wav files in two folders for bitexactness using CompAudio. In the BASOP development, the mld
tool is used as an indicator for how big the fixed point version output differs from the floating point version output. With these changes, one can also use the mld tool with batch_comp_audio which can be handy when coding a lot of files and finding the ones with the largest deviations to listen to or inspect.
No change on codec, just modifies the helper script.
