m3u8 streams are working if:
- the chunklist remains unchanged
- the sequence number is continuous
- the list from server is sent as text, not as gzip

preparations for m3u8 streams, get AACDecoder init status

can also found in lowercase

Stop if found "HTTP/1.0 404 Not Available" in playlist

not early close a valid playist if ContentType found, but read to the end

In the ASX playlist, the elements between the angle brackets <...> are sometimes upper or lower case. That is now taken into account.

and new method: getAudioDataStartPos()

is transmitted in the audio header

The variables in readMetadata () must be reset each time connecttohost () is called. If metadata is sent when changing the radio station, the metadata will otherwise be incorrectly controlled and thus errors in the mp3 decoder will occur

        if(size == m_buffSizePSRAM - m_resBuffSizePSRAM) {  // old was m_resBuffSizeRAM
            sprintf(chbuf, "PSRAM found, inputBufferSize: %u bytes", size - 1);
            if(audio_info)
                audio_info(chbuf);
            m_f_psram = true;
            f_already_done = true;
        }

Built-in DAC selection from the constructor and M5Core2+M5StickCPlus examples

unicode to utf-8 conv expanded to  < U+10000, on everything that can be displayed with uint16_t

Fix example

README: typo fix

Conclusion: ESP32 with PSRAM is too slow for ogg/flac streams
only "http://stream.radioparadise.com/flac" works yet

bitsPerSample must be 8 or 16,  fitting outBuff (int16_t) 
channels must be 1 or 2
