rlcd: fix Mp3Player pop/repetition and VoiceRecorder mic pitch

Browse Source 
- Mp3Player: increase task stack 4096->6144, prio 5->6, remove taskYIELD causing audio gaps
- VoiceRecorder: configure I2S as stereo for ES7210 (dual mic) like working MicroPython,
  then downmix left channel to mono WAV to fix low-pitch mic-like recording
