refactor

* Improve ffmpeg command to transcode flac

The command previously suggested forced the output sample rate to 48 kHz, even if the input was lower, at 44.1 kHz. 
This new command lets `ffmpeg` select the appropriate output sample rate to minimize conversion. 
Documentation: https://www.ffmpeg.org/ffmpeg-filters.html#aformat-1

* Update transcoding command

- Support more sample rates and bit depths.
- Add note about S1

-tldr; Transcoding to mp3/m4a is not supported as sonos devices will not play the track.  Transcoding to flac works however, use BNB_SUBSONIC_CUSTOM_CLIENTS=audio/flac if you want to transcode flac->flac ie. to downsample HD flacs (see below).

 Sonos devices are very particular about how audio streams are presented to them, see [streaming basics](https://developer.sonos.com/build/content-service-add-features/streaming-basics/).  When using transcoding both Navidrome and Gonic report no 'content-length', nor do they support range queries, this will cause the sonos device to fail to play the track.

 ### Audio File type specific transcoding options within Subsonic
 
 In some situations you may wish to have different 'Players' within you Subsonic server so that you can configure different transcoding options depending on the file type.  For example if you have flacs with a mixture of frequency formats where not all are supported by sonos [See issue #52](https://github.com/simojenki/bonob/issues/52) & [Sonos supported audio formats](https://developer.sonos.com/build/content-service-add-features/supported-audio-formats/)
