v0.6.1 Hotfix RC (#1635)

* Swapped out SQLite for Memory, but the one from hangfire. Added DisableConcurrentExecution on ProcessChange to avoid duplication when multiple threads execute at once.

* Fixed the Hangfire SQL issues with CPU/ram utilization some users are facing

* Fixed a case in SharpCompress fallback where an invalid ComicInfo wasn't picked up.

* When parsing epubs, if there is a volume in the epub title, try to parse and group. This is beneficial for Light Novels which are generally tagged this way.

* Fixed delete series in series detail not triggering

* Fixed some parsing logic for how we treat specials, like Annual and Omnibus.

* When scanning files, if the file is the cover image (loose leaf image), we reject it more quickly than previously.

* Added a potential bug marker

* Fixed a bug where Info was only showing Error level loggers

* Code smells
