Investigate SeaORM to replace query building logic

[insipx]

SeaORM looks to be shaping up to be a fairly full-featured ORM that has the potential to replace some of the more complex query logic for query building in archive. Most importantly the batch-query logic in batch.rs that uses string interpolation in order to form a batch call.

Testing is required to determine whether integrating SeaORM would result in performance regressions when inserting large amounts of data (particularly with storage changes).
