fix(esp_codec): calloc argument warning

[bryghtlabs-richard]

Description

Fix order of calloc arguments to address the following GCC warning:

esp_codec/audio_sonic.c:
warning: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
sonic->inbuf = (short *)calloc(sizeof(short), BUF_SIZE);

The code above is attempting to allocate a buffer of type short, with BUF_SIZE elements, but is actually asking calloc to allocate space for 2x adjacent BUF_SIZE buffers. Swap the order to address this. On ESP32, the allocated memory would be the same size anyhow.

Testing

Testing in progress. Should be a side-effect-free warning fix, but still working on getting initial examples to compile.
