Release v18.0.0 - Ads Data Refactor

This release refactors o-ads to remove the ads-api calls and instead take all targeting data passed to it via the options object. It cleans up a few other things:

• All targeting will be set through the targeting property of the options object passed to oAds.init()
• removed the ability to validate ads traffic with the moat script. This is now being done in n-ads (https://github.com/Financial-Times/n-ads/pull/77/files#diff-240938b03dfb54ca7c6bfeaa9c3f1a7fR248), or the consuming app by simply inserting the moat script on the page.
• o-ads will not call the ads-api anymore
• npm run test-unit will run jest and qunit tests
• removed ftdomdelegate package as not being used
