Populate Type table during BuildReport import #55
Description
Follow up to #47
BuildReport files to not have the string name for types.
But in #47 we introduce a list of those types (for use when we don't have the string.
This task is to use UnityFileSystem/TypeIdRegistry.cs in Analyzer/SQLite/Handlers/PackedAssetsHandler.cs and populate the type table if the type is not already present.
Once this is done we can update build_report_packed_asset_contents_view to show the string-based type instead of the numeric value, making it a lot easier to understand.
