Multiple path fragments are now supported in the built-in
`SubDirectory()` extension method, so there's no longer a need for the
custom `SubDir()` version.
It was previously located in Common, which I'm trying to gradually get
rid of. Supported services are ultimately determined by what is in the
guide, so that seems like the best place for it.
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.
