- If EOS is reached before the required number of FFTs are computed to make transfer functions, a transfer function will be written with the available data
- Added option to take a median of transfer functions instead of averaging them with a mean
- Added option to store the first transfer function computed after a gap, so that it can be used after the next gap.
