Subject: refactor: remove redundant code from crawler worker and refactor
 handling of asset types (#253)

* refactoring asset types
Extracted out functions to silently delete assets and to update them after crawling
Generalized the mapping of assets to bookmark fields to make extending them easier

* revert silentDeleteAsset and hide better-sqlite3
