If you don't want to use the FastBid adapter feature, you can lighten criteoBidAdapter size by :
1. commenting the tryGetCriteoFastBid function inner content (see ref#1)
2. removing the line 'verify' function import line (see ref#2)
Unminified source code can be found in the privately shared repo: https://github.com/Prebid-org/prebid-js-external-js-criteo/blob/master/dist/prod.js
