Feature request: support near as single chained search expression

[jkiddo]

Following up on the great work on https://github.com/hapifhir/hapi-fhir/pull/4687 https://github.com/hapifhir/hapi-fhir/issues/4650 https://github.com/hapifhir/hapi-fhir/pull/4633 it would be SO neat if the following queries could be supported:

/fhir/PractitionerRole?location.near=47.3686498|8.5391825|16.0|km&practitioner.name=Irene&_include=PractitionerRole:location&_include=PractitionerRole:practitioner&_sort=location.near

Expected response would be like the following:
