Support AAC webradio

[probonopd]

It would be nice if AAC webradio could also be supported. Some radio stations have lower bandwidth streams only available in AAC format.

#include "AudioGeneratorAAC.h"

already includes #include "AudioGeneratorAAC.h"

but then nothing is done with it.

I did some tests and it is not too hard to add this feature - right at this moment I listen to an AAC web radio station with Tasmota.

Main problem is, that this adds roughly 80 kB flash size. But this is no showstopper IMHO as I2S is optional anyway and does not enlarge any standard build.

@s-hadinger Do we want to add this feature? If yes, I would like to NOT add an additional build flag as the I2S driver is already quite fragmented. We could opt-out this later, if someone really runs into space issues.

Just remembered. Stupid me. Works great! Good quality too, on esp32s2 with PSRAM. The board costs ~3 EUR. Wow!
