Enabling the use of locations options #3
Description
Valhalla offers various locations options (such as radius, search_filter, etc., cf. https://valhalla.github.io/valhalla/api/turn-by-turn/api-reference/#locations).
I think it would be interesting to allow users to use them from valh.
For now, our functions notably take data.frame (with lat/lon columns) or sf objects as input. We could consider the other columns of the data.frames or the attributes associated with each sf point as locations options and take them into account when building the query.
