This is a fix proposal to avoid that the high priority of the separate background task
will get almost all CPU and the sketch loop() function is not called.
This happens when no audio is running as the audio.loop will return fast and called again on high priority.
When there is playing audio the separate task gets suspended while waiting for network packages,

avoid empty http authorization header

make basic authorization really optional in http header.

typo

test case: http://mcrscast.mcr.iol.pt/cidadefm
metadata are in xml format ~ 1KB and bigger (the normal length is  ~ 200 bytes)
buffer enlarged (if PSRAM found), so streamtitle can only displayed if PSRAM is available, otherwise, metadata are ignored
