New Operator in API

We have added a new operator to the API that allows you to filter a multi-select field and find records that contain any of the values you pass. The operator is called "contains_any." For example, if you have a multi-select field with three options (Basketball, Hockey, Football) and you want to find records that contain Hockey and/or Football, you can use "contains_any" with the comma-separated value of "Hockey, Football"
