Support for GORM V2

[ggrant005]

Any plans to update for use with GORM V2? The Open function has a bit different usage than V1.

I'm using it with gorm v2.

conn, _ := sql.Open(mocket.DriverName, "mockdsn")
db, err = gorm.Open(mysql.New(mysql.Config{
		Conn:                      conn,
		SkipInitializeWithVersion: true,
}))
