Add fromHook field to CompactionEntry and BranchSummaryEntry

Browse source 
- fromHook: true = hook generated, skip file extraction
- fromHook: undefined/false = pi generated, extract files (backward compatible)
- branchWithSummary now accepts fromHook parameter
- File extraction only runs for !entry.fromHook entries
