Support sqlite-utils with decimal fix.

[dvhthomas]

In order to upstream the fix in the sqlite-utils repo (simonw/sqlite-utils#110) the version dependency needs to be bumped.

That test failure is from this: https://travis-ci.com/github/simonw/db-to-sqlite/jobs/341173396

    @all_databases
    def test_db_to_sqlite(connection, tmpdir, cli_runner):
        db_path = str(tmpdir / "test.db")
        cli_runner([connection, db_path, "--all"])
        db = sqlite_utils.Database(db_path)
        assert {"categories", "products", "vendors"} == set(db.table_names())
>       assert [
            # Slight oddity: vendor_id comes out as a string even though MySQL
            # defined it as an integer because sqlite-utils treats mixed
            # integer + null as a string type, not an integer type
            {"id": 1, "name": "Bobcat Statue", "cat_id": 1, "vendor_id": "1"},
            {"id": 2, "name": "Yoga Scarf", "cat_id": 1, "vendor_id": None},
        ] == list(db["products"].rows)

Here's that comment in the code:

db-to-sqlite/tests/test_db_to_sqlite.py

Lines 13 to 19 in 187f2a1

	assert [
	# Slight oddity: vendor_id comes out as a string even though MySQL
	# defined it as an integer because sqlite-utils treats mixed
	# integer + null as a string type, not an integer type
	{"id": 1, "name": "Bobcat Statue", "cat_id": 1, "vendor_id": "1"},
	{"id": 2, "name": "Yoga Scarf", "cat_id": 1, "vendor_id": None},
	] == list(db["products"].rows)

It looks like I fixed that in simonw/sqlite-utils#94 - which shipped in sqlite-utils 2.4.3: https://sqlite-utils.readthedocs.io/en/stable/changelog.html#v2-4-3

Thanks for this - I just released 1.2 with this fix: https://github.com/simonw/db-to-sqlite/releases/tag/1.2

And now I can happily clone a Postgres database to SQLite with a one-liner. Thank you! We plan on using your sqlite tools and Datasette for an open data project around infrastructure stimulus spending for at least one U.S. state.

Fiddling with Geometry (PostGIS) data types next....
