				Summary: While looking at webhooks code, I noticed that it calls `ActiveDoc.fetchQuery` (which I think typically leads to the sandbox method `fetch_table`) with a query on the `id` column, where the values could potentially be all row IDs in the table (e.g. if a new column was added, as in a recent discussion about webhooks gone wrong). This suggests that `fetch_table` should try to avoid using a list for values when possible. In practice this only starts to become an issue at about 10k rows, so I don't know if this has caused any real problems, but it seemed like something worth fixing.
Test Plan:
Extended unit tests for correctness. Tested performance manually. Made a doc with this formula:
```
import time
row_ids = list(Table2.table.row_ids)
query = {"id": row_ids}
start = time.time()
result = table.table._engine.fetch_table('Table2', query=query)
end = time.time()
assert result[1] == row_ids
end - start, len(row_ids)
```
Then put a bunch of rows in `Table2`. This diff made the returned elapsed time much less.
