CSV posting and allow list

[karindalziel]

This issue came up in Stories of Humanity

It appears that the allow list functionality (like we use on chesnutt) only applies to filenames, not individual items. For now, the answer to this will be to delete the items we don't want to post, which isn't ideal.

For the future, I propose one of the following:

• Add a field to the spreadsheet like "Ready to publish?" and add "y" if the item is ready, change script in datura to look for "y" before posting. Datura script should allow for upper/lower case and leading/trailing spaces just in case
• change datura functionality to check for id's in spreadsheet rather than the file name when determining which items to post

I suspect the first is easier to implement, but the second might be more future proof
