Review Comment:
The same delete file object from the context is reused while making the
fileScan here.
https://github.com/apache/iceberg/blob/d42d1e89c0616c203f7ad29f002811ddd440e14f/core/src/main/java/org/apache/iceberg/ManifestGroup.java#L351
hence, I believe the default equals() is enough.
I don't disagree about having the equals and hashcode for `DataFiles` and
`DeleteFiles`. But code is widely using the `Set<DataFile>` and
`Set<DeleteFile>` already. So, if we are adding it. It should be in a separate
PR/discussion.
Let us see what others think on this.
