1. Test inferred schema for json array …

   Arrow infer schema internally uses IndexMap to keep track of inferred schema
   while updating it through given json objects. Thus the order in which
   insertion happens to this map determines the output order for schema fields
   as well.
   
   Since the json object in serde_json uses BtreeMap, the iteration is always
   ascending by key. This leads to infer_schema producing schema fields in
   ascending order when we infer using only one json object.
   In case of json array any new fields encountered are added to the last.
   Thus output order of infer schema did not provide good enough guarantee.
   This is solved in parseablehq#450. This commit just adds a test for it.
