[PERFECT] A2DP Sink test of LHDC V5 at 192kHz/24bit on ESP32-CAM (esp32-d0wd, N4R8) powered by a2dp-codecs/v6.1.0 #1

Branch a2dp-codecs/v6.1.0 is a fork of @WillyBilly06 's LHDC V5's embeded esp-idf-v6.1-codecs. I separated it out and rebased it onto what I consider the correct official @espressif s' esp‑idf commit, so that all modifications are faithfully recorded.

I test a full music with LHDC V5 at 192kHz/24bit, I think it is much more perfect than any effects I have. I really enjoy the effect! There is 0 stuck, 0 pop, sample rate changed faster than the old branch a2dp-codecs/v5.1.4 !

The demo is in repository MLX_Player_ClassicBT/tree/dev/v6.1.0 .

TIPS: remove dependencies.lock, or replace ../../../Espressif/frameworks/v6.1.0/esp-idf with ${IDF_PATH} before build the project. cmake will auto change it to your true esp-idf path.
