Support "IBM-style" filtering

[michael-dean-haynie]

Reference: https://www.jsonapi.net/usage/reading/filtering.html

For existing "mongodb-style" filtering reference: https://canjs.com/doc/can-deparam.html and https://www.mongodb.com/docs/manual/reference/operator/query-comparison/

Also consider:

• user might use both styles in the same querystring
• user may want to use multiple filters in same query string
