.NET 6 Coding Patterns + Unit Tests (#823)
* Refactored all files to have Interfaces within the same file. Started moving over to file-scoped namespaces.

* Refactored common methods for getting underlying file's cover, pages, and extracting into 1 interface.

* More refactoring around removing dependence on explicit filetype testing for getting information.

* Code is buildable, tests are broken. Huge refactor (not completed) which makes most of DirectoryService testable with a mock filesystem (and thus the services that utilize it).

* Finished porting DirectoryService to use mocked filesystem implementation.

* Added a null check

* Added a null check

* Finished all unit tests for DirectoryService.

* Some misc cleanup on the code

* Fixed up some bugs from refactoring scan loop.

* Implemented CleanupService testing and refactored more of DirectoryService to be non-static.

Fixed a bug where cover file cleanup wasn't properly finding files due to a regex bug.

* Fixed an issue in CleanupBackup() where we weren't properly selecting database files older than 30 days. Finished CleanupService Tests.

* Refactored Flatten and RemoveNonImages to directory service to allow CacheService to be testable.

* Finally have CacheService tested. Rewrote GetCachedPagePath() to be much more straightforward & performant.

* Updated DefaultParserTests.cs to contain all existing tests and follow new test layout format.

* All tests fixed up
