- add eclipse project configuration

- use espressif ADF, remove external opus rep
  o uses audio pipelines now
- change code to use flac decoder
- remove mersus code
- add first try of audio synchronization
  o needed to sync timeofday to server on reception of server settings to avoid overflows in timeval calculations (int32_t on esp32 SDK)
  o still a lot of TODO's in the code, but it's almost in sync, although there is quite some chunk skipping which I am currently working on
