Description of change

Type checking was added to the values that are both user and prebid provided following an issue where validBidRequests[0].userId.tdid was an object instead of a string which caused our backend to return a 400 error.

We now check that the type of the input is of the type our API expects (or can be coerced to that type). If an invalid type is present, we report that information to the API in root.ext.krg.verr for alerting purposes. In some cases, we will also logError the correct format so publishers can see the issue.

As part of increasing the type strictness, we also now validate the placementId parameter more closely in isBidRequestValid making sure that it is present, is a string, and starts with _ (which all valid placementIds do).
