Errors in Cloudflare Workers environment with recent versions

[primeare]

Introduction

Cloudflare in their documentation propose to use mimetext for sending emails in their Cloudflare Workers and Cloudflare Email Workers.

The problem

Since updating to version 3.0.21 (although it could be any version after 3.0.16, as it worked previously), the library does not work natively in the Cloudflare Workers environment. By saying natively, I mean without transpiling code or enabling Node.js compatibility modes or flags.

Hotfix solution

Currently, I found two possible solutions:

1. Use browser version of mimetext: import { createMimeMessage } from 'mimetext/browser';;
2. Enable node_compat = true in wrangler.toml to turn on Node.js polyfills.

Node.js version: 18.19.0

hey @primeare they look like good solutions, and i think they should be in the readme under use section. create a pr if you wish or i will soon update the readme and include this.

ps: i will test the the library in cloudflare worker environment later and come up with a proper solution

I just use mimetext/browser for this. Worker-d runs on web standards
