- 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
