@technoweenie I'm having issues uploading the asset as the body of the request, it's probably something that I'm doing wrong.

- I pass the file as a body for the request, since it's an *io.Reader.
- The url where I send the request is something like this: `https://uploads.github.com/repos/calavera/testGoPack/releases/128568/assets?name=1.txt`
- The content type is detected as `text/plain` which is correct.

The api gives me a status code 422, which is "Unprocessable entity".

Any recommendation?
