AAC+ support

[zdzisius]

Hello,

I have noticed that there is an update (v 3.0.0) to this fantastic library which supporting aac+ format now. Actually I have a question here, is it possible to have a good quality of sound for the aac+ internet radio? I use esp32-wroover + pcm5102a. The problem is the quality is really low - mono and 47k. Is it related to the version of esp32 or maybe something else?

here is the console log:

It is difficult to retrofit 'Parametric Stereo' into existing decoders. AACP is therefore considered mono for the time being.
