The documentation for `sqlite3.paramstyle` states that only `qmark` and
`numeric` styles are supported for parameter placeholders but, according
to the SQLite documentation, the `named` style is also supported.

See the following links for more details:

A simple example confirms that this is supported:

```pycon
>>> import sqlite3
>>> con = sqlite3.connect(":memory:")
>>> cur = con.execute("CREATE TEMPORARY TABLE t (name TEXT)")
>>> cur.execute("INSERT INTO t (name) VALUES ('Bob'), ('Cat'), ('Joe')")
<sqlite3.Cursor object at 0x7fcbe373b940>
>>> cur.execute("SELECT * FROM t WHERE name = :name", {"name": "Cat"})
<sqlite3.Cursor object at 0x7fcbe373b940>
>>> print(cur.fetchone()[0])
Cat
```
