Provide configuration hook in constructor of NativeSqliteDriver

[svenjacobs]

Description

As commented here I would like to suggest an enhancement of the NativeSqliteDriver constructor.

For example if I just want to enable foreign keys, I have to write a lot of boiler plate code. I suggest an optional onConfiguration callback to hook into the configuration.

constructor(
    schema: SqlDriver.Schema,
    name: String,
    maxReaderConnections: Int = 1,
    onConfiguration: (DatabaseConfiguration) -> DatabaseConfiguration = { it },
) : this(
    configuration = DatabaseConfiguration(
        name = name,
        version = schema.version,
        create = { connection ->
            wrapConnection(connection) { schema.create(it) }
        },
        upgrade = { connection, oldVersion, newVersion ->
            wrapConnection(connection) { schema.migrate(it, oldVersion, newVersion) }
        }
    ).let(onConfiguration),
    maxReaderConnections = maxReaderConnections
)

Usage would look like

NativeSqliteDriver(
    schema = Database.Schema, 
    name = "database.db",
    onConfiguration = { config ->
        config.copy(
            extendedConfig = DatabaseConfiguration.Extended(
                foreignKeyConstraints = true,
            )
        )
    }
)

I'm happy to provide a pull request if this is a desired change.
