add functionality for array parameters in query

[bauerji]

Added functionality to use list fields in query params.

When using query model

class QueryMode(BaseModel):
    a: List[str]

the api call /whatever_endpoint?a=one&a=two results in request.query_params.a having the value ["one", "two"]

closes #7
