57e43baece Table options can now be passed to constructor OR to insert_all()
If you want to set default options for a table, you can do this:

    table = db.table("dogs", pk="id", column_order=["name", "age"])

If you pass those keyword arguments to the .insert/.update/etc
methods they will over-ride the defaults you set on the table.

    table = db["dogs"] # This still works too

00c5a49a87 Option to ignore inserts if primary key exists already
Support for SQLite's INSERT OR IGNORE

In the API layer it looks like this:

    fresh_db["test"].insert({"id": 1, "bar": 3}, ignore=True)

For the CLI layer it looks like this:

    $ sqlite-utils insert data.db dogs dogs.json --ignore

e1ca938aa1 table.add_foreign_key(column, other_table, other_column)
New mechanism for adding foreign key constraints to an existing SQLite
table.

SQLite ALTER TABLE does not support this out-of-the-box, so I instead
had to write some careful code that uses PRAGMA writable_schema = 1 to
directly modify the sqlite_master table.

82f0f6076a sqlite-utils insert db.db foo - --csv
New option for efficiently inserting rows from a CSV.

Uses a generator so this will happily consume enormous CSV files without
needing to slurp the whole thing into memory first.
