• add support for sample rates different to 48kHz (#15)

  - instead of storing chunk duration in ms store the frame count
    and do calculations based on that
  - add updated snapserver.conf for reference (#17)
  - some code clean up
  - move Kconfig entries to correct place
  - remove unnecessary Kconfig entries
  - add necessary dependencies in Kconfig files

• - add sdkconfig for NO_SPIRAM and SPIRAM situation

  - detect snapcast configuration and init everything accordingly, e.g sample rate, chunk duration, ...
    o calculate apll predefines in dependence of sample rate
    o communicate these settings to interested parties
  - remove typos

• - merge with original master from jorgen

  - minimize RAM usage of all components
  - use both IRAM and DRAM in player component so we can buffer up to 1s on modules without SPI RAM
  - support fragemented pcm chunks so we can use all available RAM if there isn't a big enough block available but still enough HEAP
  - reinclude all components from jorgen's master branch
  - add custom i2s driver to get a precise timing of initial sync
  - change wrong usage of esp_timer for latency measurement of snapcast protocol
  - add player component

• - 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
