Commit 004dbb0

[tv4you2016]

hello, @schreibfaul1

I'm using your lib and it was working 100%.

After updating the lib to the latest commit 0d590b7, I noticed that the stream was playing slowly.

I went back and saw that this started in commit 004dbb0

Any suggestions? I've used several radios and they all have the same issue.

In the last version I had installed a modern mp3 decoder. This runs very well on the S3. The ESP32 is too slow for this. It would work if I moved various buffers from the PSRAM to the SRAM and replaced frequent bit operations with XTENSA asm.
Access to the PSRAM is simply too slow with the ESP32 and some arithmetic operations take more than twice as long as with the S3.
I have reactivated the old Helix mp3 decoder.
In the long term, the ESP32 will probably be obsolete after 7 years, just like the 8266 was back then.
