Synchronisation is a bit of a hack with i2s. The esp32 driver is always
full when it starts, so there is a delay of the total length of buffers.
In other words, i2s_write blocks at first call, until at least one buffer
has been written (it uses a queue with produce / consume).
The first hack is to consume that length at the beginning of tracks when
synchronization is active. It's about ~180ms @ 44.1kHz
The second hack is that we never know exactly the number of frames in the
DMA buffers when we update the output.frames_played_dmp. We assume that
after i2s_write, these buffers are always full so by measuring the gap
between time after i2s_write and update of frames_played_dmp, we have a
good idea of the error.
The third hack is when sample rate changes, buffers are reset and we also
do the change too early, but can't do that exaclty at the right time. So
there might be a pop and a de-sync when sampling rate change happens. Not
sure that using rate_delay would fix that
