Deno support

[David Dal Busco]

Is your feature request related to a problem? Please describe.

I tried to integrate agent-js in a Supabase function which uses Deno but, build failed.

❯ npx supabase functions deploy cron-statuses
Version 1.30.3 is already installed
Bundling cron-statuses
Error: Error bundling function: exit status 1

Try rerunning the command with --debug to troubleshoot the error.

For sample code:

import { serve } from "https://deno.land/std@0.168.0/http/server.ts"
import {Ed25519KeyIdentity} from "https://esm.sh/@dfinity/identity";

console.log("Hello from Functions!")

const key = Ed25519KeyIdentity.generate();
console.log("Key", key);

serve(async (req) => {
  const { name } = await req.json()
  const data = {
    message: `Hello ${name}!`,
  }

  console.log('LOG:', data.message);

  return new Response(
    JSON.stringify(data),
    { headers: { "Content-Type": "application/json" } },
  )
})

Verified still not working in Feb '24. Unfortunately, I don't think we can fix this until we replace the borc dependency
