feat(upload): Added body to download function

[enri90]

Added post functionality to the download function
Example

const body = JSON.stringify({ ids: ids });

await download(
  url,
  path,
  ({ progress, total }) => console.log(`Downloaded ${progress} of ${total} bytes`),
  new Map<string, string>([
    ['Content-Type', 'application/json'],
  ]),
  body
);

Sorry for the long delay in your first PR. What do you think about leveraging the native Request object for the url and body?

Basically mirroring the http plugin: https://github.com/tauri-apps/plugins-workspace/blob/v2/plugins/http/guest-js/index.ts#L104

Let me know what you think and whether you'd be open to work on it (if you agree) or if i should take over :)

Hi! Thank you for the feedback.
I understand the request to leverage the native Request object for the URL and body and think it's a good idea.
However, I'm not very familiar with Rust and am not sure how to implement this.
If you could take over this part, that would be fantastic.
Thanks!

Okay sure, no problem!
