[Feature Request] Kavita - Allow cover locking

[CPU-Blanc]

Hello! Been using komf for a while now and it was working great until recently when all my cover images generated by komf are being replaced by the first page of the first chapter. A little poking and it seems as though komf is updating the series cover image as requested, but kavita then rescans the series and generates a new cover image, removing the old one. I'd like to have komf manage all of my cover images as it used to. Could a new config option be made to allow komf to lock the kavita cover image to prevent kavita messing with it? Unless this is an unintentional regression?

My current config

kavita:
  eventListener:
    enabled: true # if disabled will not connect to kavita and won't pick up newly added entries
    metadataLibraryFilter: [ ]  # listen to all events if empty
    metadataSeriesExcludeFilter: ["157"]

  metadataUpdate:
    default:
