dr14 shows only one bit depth / sample rate in case when folder contains FLAC files with different specs

[maplee0]

Hello!
When it's run in folder that contains files with different specs it returns only one bit depth / sample rate for all of them.
python3 "./dr14_tmeter.py" "$PWD"
For example:
File 1.flac is 16 bit / 44.1 kHz
File 2.flac is 16 bit / 48 kHz
File 3.flac is 24 bit / 96 kHz

Result log will include all these files, but it shows that all these files are 16 bit / 44.1 kHz.

Some news about this bug?

Would this type of report meet your requirements?

 Sampling rate: 		 various - ['48000', '96000'] Hz
 Average bitrate: 		 1655 kbs 
 Bits per sample: 		 various - ['16', '24'] bit

The perfect way to implement exact specs would be like foobar2000 does it. It adds result line and tech data for each different sampling rate or bit depth and average bitrate is calculated only for tracks with the same sample_rate/bit_depth. For example:

foobar2000 2.0 / Dynamic Range Meter 1.1.1

Another way is adding exact sampling rate and bit depth for each track:
Sampling rate: tracks 1, 5, 7 - 44100 Hz; tracks 2, 3 - 48000 Hz, etc.
Bits per sample: tracks 1, 4, 6 - 24 bit; tracks 2, 5, 7 - 16 bit.
