Error when assigning cluster IDs

[masonyoungblood]

Hi Nilo!

I'm working on analyzing some pre-segmented birdsong syllables in pykanto, and I'm hitting an error when I run dataset.cluster_ids(). Do you know what the issue might be? Here's the error:

---------------------------------------------------------------------------

The above exception was the direct cause of the following exception:

KeyError: 'ID'

In case it's an issue with the "ID" field in my JSON files (which I'm making from scratch to match the examples in the repository), here's an example of what one looks like (many fields are random btw):

{
 "species":"Kauai Oo",
 "ID":"kauai",

Let me know if any other details would be helpful, and thanks in advance! :)
