DaVinci Resolve export "Clip was not found" due to `<pathurl>` having back slash instead of forward slash

Bug description

I've tried --export resolve, --export premiere, and --export final-cut-pro, and it all produces the same "Clip was not found" error upon importing the XML to DaVinci Resolve 18.6.5. I can work around this issue by changing the back slashes to forward slashes in <pathurl>.

For example, Auto-Editor produces the following: <pathurl>E:\Stream VODS 2024 Q1-2\2024-03-10_13-52-45.mkv</pathurl>

The issue goes away when I manually change it to this: <pathurl>E:/Stream VODS 2024 Q1-2/2024-03-10_13-52-45.mkv</pathurl>

I don't know if other Resolve users have experienced the same problem with the current version of Auto-Editor. This was not an issue when I used a compiled binary that a Redditor had made based on version 22w18a.

Lastly, thank you for creating Auto-Editor! I wish I discovered this program sooner. It has been a huge help.
