Extra parameters for Lookup API

The lookup API offers an optional query parameter extras that allows requesting a list of extra fields that are by default not included in the responses. Multiple values in that list must be separated with +. Some combinations of extras and sources are not supported, in that case the extra is ignored.

Be aware that these extras don't come for free; each of them has a negative impact on the response time of the Lookup API. Only request them if you need them.
