An issue with handling blip without embed

[savinskiy-konstantin]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Part of pptx slide structure:

<p:blipFill>
    <a:blip>
        <a:extLst>
            <a:ext uri="{79A0055B-C67C-407E-A111-50E730381C1C}">
                <a14:useLocalDpi
                    xmlns:a14="http://schemas.microsoft.com/office/drawing/2010/main"
                    val="0"/>
            </a:ext>
        </a:extLst>
    </a:blip>
    <a:srcRect/>
    <a:stretch>
        <a:fillRect/>
    </a:stretch>
</p:blipFill>

Today I used patch-package to patch [email protected] for the project I'm working on.

Here is the diff that solved my problem:
