Review Comment:
Also pointing out: I could've avoided changing existing code entirely and
having a completely independent class for append scans with duplicated manifest
planning logic. I felt as though:
- the hierarchy with `TableScan` and `DataScan` (prior to this PR) would
then feel odd with a fully independent `IncrementalAppendScan`
- duplicated code is code smell, so I've gone with a refactor here. To note
that it's largely just moving code around than anything else! Let me know what
folks think or design suggestions here, very open to changes
