[FEATURE]: Export factory functions from `drizzle-zod` to allow usage with extended Zod classes

[juliusmarminge]

Describe what you want

To allow generating schemas from an extended Zod class, such as: https://github.com/honojs/middleware/tree/main/packages/zod-openapi

Currently, this doesn't work since generated schemas are using the default z object which will cause runtime errors if later combined with .openapi() from the lib above

Something like this would be nice

import { z } from '@hono/zod-openapi'
import { createInsertSchemaFactory } from 'drizzle-zod/factories'

import { User } from '~/schema'

const createInsertSchema = createInsertSchemaFactory(z);

const InsertUser = createInsertSchema(User)

// later

InsertUser.openapi() // works

This would be very helpful. I don't understand how people use Hono with Drizzle without this, is everyone duplicating their source of truth?
