Could provide a template for using a third-party decoder, similar to the template for "my_board"? (AUD-4974)

Is your feature request related to a problem? Please describe.

When using the default library, we do it like this:

              //   mp3_decoder_cfg_t mp3_cfg = DEFAULT_MP3_DECODER_CONFIG();
              //   audio_element_handle_t mp3_decoder = mp3_decoder_init(&mp3_cfg);
              //   esp_audio_codec_lib_add(player, AUDIO_CODEC_TYPE_DECODER, mp3_decoder);
              //  //    audio_pipeline_register(pipeline, mp3_decoder , "dec");

When I want to use a third-party decoder:

For example, how can I use the following code to decode a WAV file?

              uint32_t recvSize = 0;
              do
              {
                recvSize =  file.read((void*)buffer, 1024);

                for(uint32_t i = 0;i<recvSize/2;i++)
                {
                  partWavData[2*i] = buffer[i];   
                  partWavData[2*i+1] = buffer[i]; 
                }

                mi.Write((char*)partWavData, recvSize*2); //i2s_write

                  // startPos += recvSize;
                  // file.seek(startPos);
              }while(recvSize>0);
              file.close();

Could provide a template for using a third-party decoder, similar to the template for "my_board"?

That's a good idea. I think we can provide an example like this.

That's great! I hope to be able to use it soon.
