The cache system has been redesigned for extensibility and to support
caching data beyond Custom Formats. This is motivated by plans to cache
Quality Profiles to support the ability to do things like rename
profiles.
To simplify logic in the system, a child lifetime scope is created for
each distinct configuration instance that is processed by Recyclarr. The
main driver for this is to avoid objects being reused between instances
and thus needing setup & teardown logic to deal with state.
- `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.
