Support Migrations (CreateTableBuilder)

[Fyko]

Heyo, thank you for creating this package! It would be amazing if we could use Kysely's migrations system to add a column with the type geometry, such as the following:

export async function up(db: Kysely<any>): Promise<void> {
	await db.schema.createTable('property');
		// other columns
		.addColumn('coordinate', 'geometry')
		.execute();
}

In the meantime, doing sql`geometry` works.

I will need to use module augmentation to do that not sure if I will implemented it as sqlgeometryis easy to use.

I keep it open for now :)
