Reproduced step

Steps to reproduce the behavior:

1. create a document with an image in the header or footer
2. import that document using readDocx
3. image is not present

@bokuweb could you please look into this? Thank you.

@gjblajian Sorry for late. I'm busy now... I'll improve it.

Images in headers (and probably footers) are also broken when created programmatically

use docx_rs::{Docx, Header, Paragraph, Pic, Run};
use std::{error::Error, io::Cursor};

fn main() -> Result<(), Box<dyn Error>> {
    let cat = Pic::new(include_bytes!("cat_min.jpg"));
    let header =
        Header::new().add_paragraph(Paragraph::new().add_run(Run::new().add_image(cat.clone())));
    let mut out = Vec::new();
    let docx = Docx::new()
        .header(header)
        .add_paragraph(Paragraph::new().add_run(Run::new().add_image(cat)));
    docx.build().pack(Cursor::new(&mut out))?;
    std::fs::write("/tmp/out.docx", &out)?;
    Ok(())
}
