Upload a CoA addition

Attach a supplementary document to the sample, alongside its CoA. Additions accumulate, so each upload adds another file.

Allowed extensions are pdf, jpg, jpeg, png, gif and bmp, and additions can only be added while the order is in progress (status_id 3) - otherwise the endpoint returns the invalid_order_status error.

Send the file as a file field in a standard multipart/form-data request, and leave file fields out of signature generation.
