Set the values of multiple custom fields for a given object in a single call.
This is the recommended approach when updating multiple fields on the same object
to avoid race conditions that can occur with concurrent customField.setValue calls.

Pass fieldValue: null for an entry to clear that custom field.

Note: To set custom fields on an Employee, use user.setCustomFieldValues instead. To set them on a Job Posting, use jobPosting.setCustomFieldValues instead.

The values accepted in the fieldValue param depend on the type of field that's being updated. See the customField.setValue docs for the full per-type table.
