Pass custom props to the `email build` command

• Component or Package Name: jsx-email
• Component or Package Version: any

Feature Use Case

I want to use jsx-email with Golang, and in order to do that, I need to render the emails to HTML first and then import them as strings/files in my Golang app. My email templates have some custom properties that I want to set dynamically while building the HTML files.

This should potentially allow the use of templates created by JSX-email with almost any programming language.

Feature Proposal

Let's say we have this template:

import { Button } from 'jsx-email';

const Email = ({ title }) => {
  return (
    <Button href="https://example.com" style={{ color: '#61dafb', padding: '10px 20px' }}>
      {title}
    </Button>
  );
};

I want to be able to do something like this:

email build ./email.tsx --title="Click me"

Being able to pass custom props to the CLI tool allows to generate emails programmatically in any language that supports spawning new CLI processes.

Hey thanks for the issue. This is already possible with the --props flag, which accepts JSON. Run email help build for a full list of flags for that command.
