Import png attachments as binary using esbuild

[rt-joe]

Hello, big fan of react-email! Thanks for all you do.

We load some png files as binary to load as attachments, example:

interface Attachment {
  filename: string;
  content: Buffer;
  cid: string;
}
import myImage from "./my-image.png";
export const myImageAttachment: Attachment = {
  filename: "my-image.png",
  content: myImage,
  cid: "myimage",
};

We use esbuild to bundle, and add the following config in order to load the files as binary

    loader: {
      ".png": "binary",
    },

When trying to run dev server with email dev we get the error src/attachments/index.ts:2:22: ERROR: No loader is configured for ".png" files: src/attachments/my-image.png

Is there any workaround for this? Or is there a way to set options for the esbuild command used under the hood by react-email cli?

This comment thread has similar question: #1403 (reply in thread). I think reading the file using node would work for dev env but then I would have to dynamically swap out which attachments I'm referencing based on whether I'm running local dev server or not. Curious what other options there may be. Thanks!
