- 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
