Todos 🧰

• Add a middleware that extends ctx with ctx.replyWithPagination, so that you can display the first page of pagination without developer integration ( only for displayType "text")
• Add more advanced(optimized) logic for memoization dynamicData
• Add "numbers" schema
• Add debug's with https://deno.land/x/debug/mod.ts
• Add session cleanup if pagination is not used
