Rationale for this change
Split up from incremental append scan work - see #2031 (comment). PyIceberg doesn't support incremental reading of appended data between snapshots, like Spark does.
This PR adds equality and hash notions to
ManifestFile, because for incremental reading, we construct a set of manifest files. See #2233 (comment).Are these changes tested?
N/A
Are there any user-facing changes?
Technically yes, manifest equality now works via the introduced semantics
