Subject: [PATCH] Adapt the max capacity of
 AudioFormatWriter::writeFromFloatArrays

Currently this operation is limited and asserts if the incoming audio buffer
has more than 255 channels. Since `chans` is a vector, it seems straightforward
to adapt its size and support any value of `numSourceChannels`. This will also
spare the creation of 256 int pointers when buffers of less than 255 channels
are written.
