Subject: [PATCH] CollectionSettingsPage: add option to toggle
 `libebur128`-based song analysis

Much like song fingerprinting, performing EBU R 128 analysis is optional.

If you will want to enable EBU R 128 loudness normalization
(which does not depend on the presence of `libebur128`!)
you will probably want to enable it, but it is not enabled by default.

There will be support for rescanning songs for which it is missing.
