/* NB: This junk chunk is added for padding, so that the header is a fixed size
regardless of whether it's RF64 or not. That way, we can begin recording a file,
and when it's finished, can go back and write either a RIFF or RF64 header,
depending on whether more than 2^32 samples were written.
The JUCE_WAV_DO_NOT_PAD_HEADER_SIZE macro allows you to disable this feature in case
you need to create files for crappy WAV players with bugs that stop them skipping chunks
which they don't recognise. But DO NOT USE THIS option unless you really have no choice,
because it means that if you write more than 2^32 samples to the file, you'll corrupt it.
