Adapt the audio-channel capacity of AudioFormatWriter::writeFromFloatArrays
Saving an audio file with many audio channels hits a limit (and asserts) at 255.
https://github.com/juce-framework/JUCE/blob/9055820a30770479e30994c9a91029474cf60f7d/modules/juce_audio_formats/format/juce_AudioFormatWriter.cpp#L160
After a quick glance at the git history: it seems like chans was formerly a
C-array (hence the static limit), and then was converted to a vector of the
same fixed size in 31a7c62bafe87626578e0cda7db138c78d10d9db.
It doesn't seem like there's anything on the way of making its size adapted to
the incoming audio buffer (numSourceChannels + 1).
This will also spare the creation of unused channels with buffers of less
than 255 channels.
