[BUG] 16-bit tracks are incorrectly converted to 24-bit

Describe the bug

The config file states that bit_depth in the conversion section is only applied if the bit depth is higher than the specified value. However, if I specify a bit depth of 24 and download a 16-bit album from qobuz, it incorrectly converts the files to 24-bit. sampling_rate is correctly applied however, in that if I specify a sampling rate of 48000, a file with a sampling rate of 44100 is not upsampled.

In other words, if my config settings are set to bit depth of 24 and sampling rate of 48000, downloading a 16/44100 track results in a 24/44100 file when I would expect it to remain 16/44100.
