converter/tospdif: convert DTS 14bit to DTS 16bit
DTS inside WAV (@44.1kHZ) use 14bits words and have a fsize of 4096 bytes for
1024 samples. This means there is no room to put the IEC61937 header (IEC frame
size = 4096 = fsize = 1024 samples x 4).
Before this commit, we sent the IEC61937 frame without the header, this worked
only for some receivers.
This commit converts the 14bit sample to 16bit in order to have room for the
IEC61937 header. The new fsize is 4096*14/16 = 3584, so there is room for the 8
bytes header (plus 0 padding until 4096).
