Error when Blogger draft has no title: throw er; // Unhandled 'error' event

[levid0s]

When I ran blog2md on my Blogger export, it crashed with the following error:

PS D:\temp\blog2md> ..\node-v18.14.2-win-x64\node.exe index.js b .\blog-03-04-2023.xml ./myblog

I realised this was caused by an unpublished draft from 2014 that didn't have a title configured.
After adding a title on Blogger, and downloading a new .xml export, blog2md worked sucessfully.
