Subject: [PATCH] Add `upsertStreaming` and `upsertBatch` (fix #115) (#117)

* Add `upsertStreaming` (fix #115)

* Add `upsertBatch` repo method.

caveats:
- anorm didn't support returning rows for batch queries, so it's monkey-patched in into the `anorm` package
- zio-jdbc cannot express batch updates at all. For this reason it was necessary to add support for not implementing a repo method for a dblib.

* fix upsert for tables where all columns appear in id
