Attachment KeyError Issue (Including Patch)

[svandragt]

Hello, thanks for writing Todoist Converter! I've used it to convert from Todoist to OmniFocus via Taskpaper and it's worked well!

I had some uncommon Todoist tasks that wouldn't convert using this tool because the attachment field had unexpected data in it. I suspect this is populated using the IOS share sheet from another app. This caused a KeyError meaning the output would skip any following task items.

I've enclosed a patch which passes when a KeyError occurs so that the task (and any following) are still exported, even though the attachment might be missing.

This is the error:

Traceback (most recent call last):
