v0.17.0

• Update dependencies
• Adds AttachmentsField
• object type schemas with attachment=true render AttachmentsField and attach _id properties to their appropriate section of formData
  • this randomly generated 10 character alphanumberic id is used to identify/match which field uploaded attachments should be assigned to.

// can place attachments property on any object type field
const schema = {
  type: 'object',
  attachments: true,
  ...
};

// accepted mime types can be applied using field specific ui:options
const uiSchema = {
  'ui:options': {
    accept: 'application/pdf, image/*',
  },
};

newly generated formData example
const formData = {
  section: {
    firstName: 'Testy' // form field value
    _id: asdfg12345 // field id
  }
};

attachments uploaded through an `AttachmentsField` should carry the matching `_id` so that they may be displayed in their appropriate sections

New required formContext properties:

const formContext = {
  attachmentDestinationId, // i.e. EKID of access-request
  onDrop,
  onDeleteAttachment,
  attachments,
  formRef,
};

type OnDrop = (
  file :Object,
  attachmentDestinationId :UUID,
  fieldId :string,
  formData :Object,
) => void;

type OnDeleteAttachment = (
  attachment :Object,
  formData :Object
) => void;

type Attachment = {
  date :string;
  fieldId :string; // id of attachments field to inform render target
  href :string;
  id :UUID; // entity key id of file
  name :string;
  type :string;
};

type Attachments = {
  [fieldId :string] :Attachment[];
}
