update from master

fix ESP crashes during playing local MP3 file with ID3 Tag v2.2 #460

keep the test branch up to date

If there is metadata behind the audio block and it is a local file, it will now be read
new function 'seek_m4a_ilst()' // item list atom, contains the metadata

indata underflow in decodeNextElement()

make thread safe

for critical areas:
    xSemaphoreTake(mutex_audio, portMAX_DELAY);
    xSemaphoreGive(mutex_audio);

for areas that can be called by their own thread
    xSemaphoreTakeRecursive(mutex_audio, portMAX_DELAY);
    xSemaphoreGiveRecursive(mutex_audio);
