SBA printout: add Ambisonic order info

It is proposed to print out also the SBA order of IVAS SBA format to stdout.

Baseline:

Max. encoded bandwidth: FB
Input sampling rate:    48000 Hz
Bitrate:                32.00 kbps
IVAS format:            Scene Based Analysis

With the fix:

Max. encoded bandwidth: FB
Input sampling rate:    48000 Hz
Bitrate:                32.00 kbps
IVAS format:            Scene Based Analysis, Ambisonic order 1
