Support partial overwrites

[Fokko]

Feature Request / Improvement

The current Table.overwrite(pa.Table, BooleanExpression) allows us to overwrite parts of the table that match the predicate. Currently only AlwaysTrue() is supported, which means a full overwrite.

@Fokko if nobody is already looking at this, would love to try and take a stab at this?

@whynick1 This should be done once #554 is in. Would you like to provide one of the metadata tables? See #511

Closing this since it is a duplicate of #511. A partial overwrite is essentially a delete + append.

@Fokko In that case, can I take #554, if not I am happy to work on #511 too.
