Find campaign clickers Salesforce does not know about yet

**Objective:** Find everyone who clicked a link in the Mailchimp campaign titled `{campaign-title}` and has no contact or lead in Salesforce with the same email address, returning up to `{max-records}` people (default 50).

**Step 1: Find the campaign**

Call `mailchimp-get-campaign` with `title.contains` set to `{campaign-title}`. If more than one campaign matches, list them with their send-date and campaign-id and stop so the user can choose. If none matches, say so and stop.

**Step 2: Collect the clickers**

Call `mailchimp-get-campaign-email-activity` with that `campaign-id` and `action` set to click. Reduce the result to unique email addresses. Use `mailchimp-get-campaign-recipient` with the same `campaign-id` and the `email-address` to fill in first-name, last-name and company for each one.

**Step 3: Check each clicker in Salesforce**

For each email, call `salesforce-get-contact` with `email` set to that address. If no contact matches, call `salesforce-get-lead` with `email` set to that address. Stop checking once `{max-records}` unmatched people have been found.

**Step 4: Report**

A table of the unmatched clickers: email, first name, last name, company, number of clicks and the last click date. Below it, one line giving the totals: clickers checked, matched to a contact, matched to a lead, unmatched.

**Rules & Guidelines:**

* `mailchimp-get-campaign`, `mailchimp-get-campaign-email-activity` and `mailchimp-get-campaign-recipient` are on the mailchimp server. `salesforce-get-contact` and `salesforce-get-lead` are on the salesforce server.
* This prompt is read-only. Do not call `salesforce-add-lead` or `salesforce-add-contact`. To create leads from this list, use the create-leads-from-campaign-clickers prompt.

**Validation:**

* Compare email addresses case-insensitively and trim spaces.
* If the campaign has no click activity, say so and stop.
* If every clicker is already in Salesforce, say so rather than returning an empty table.
