The removal of Sonarr v3 support (commit d45563cf) introduced a bug
resulting in media naming no longer working due to the `:4` key suffix
not being checked anymore.
Additionally, there were some tests under `src/tests/` that needed to be
moved to `tests/`. One of these tests in particular helped identify this
bug. Those tests have been moved to the appropriate location.
- `CustomFormatCache` is now a utility class for updating cache entries.
- `CustomFormatCacheData` is now what `CustomFormatCache` used to be
(data object used for serialization).
- `CustomFormatCachePersister` is now specific to custom formats. Future
cache types will have their own persister implementation.
This was originally put in place in commit b0bbb23d3 (from 2021) to
silence analysis warnings. However, I observed no warnings so this must
have been corrected in dotnet since then.
