This commit modifies 02dbed6e to use band->active_lines to better gauge how much information is contained within a single band and thus allow the perceptual noise subsitution to more accurately determine which bands to code as noise. The spread[w+g] used before this patch behaved more like a low-pass filter for PNS band_types, which could mistakingly mark some low frequency bands as noise.

The loop always needs at least 8 bytes for chunk_type and chunk_size.
If fewer are left, bytestream2_get_le32 just returns 0 without
reading any bytes, leading to an infinite loop.

This returns something like "v12_dev0-1332-g333a27c". This is much more
useful than the individual library versions, of which there are too
many, and which are very hard to map back to releases or git commits.
