       Some MongoDB commands return a "cursor" document. For example, given an "aggregate" command:

          { "aggregate" : "collection", "pipeline" : [], "cursor" : {}}

       The server replies:

          {
             "cursor" : {
                "id" : 1234,
                "ns" : "db.collection",
                "firstBatch" : [ ]
             },
             "ok" : 1
          }

       mongoc_cursor_new_from_command_reply is a low-level function that initializes a mongoc_cursor_t from such
       a reply. Additional options such as "tailable" or "awaitData" can be included in the reply.

       When synthesizing a completed cursor response that has no more batches (i.e. with cursor id 0), server_id
       may be 0. If the cursor response is not completed (i.e. with non-zero cursor id), pass the  server_id  of
       the server used to create the cursor.

       Use  this function only for building a language driver that wraps the C Driver. When writing applications
       in C, higher-level functions such as  mongoc_collection_aggregate()  are  more  appropriate,  and  ensure
       compatibility with a range of MongoDB versions.

       • client: A mongoc_client_t.

       • reply: The reply to a command, such as "aggregate", "find", or "listCollections", that returns a cursor
         document.  The  reply  is  destroyed  by  mongoc_cursor_new_from_command_reply and must not be accessed
         afterward.

       • server_id: The opaque id of the server used to execute the command.

       A mongoc_cursor_t. On failure, the cursor's error is set. Check for failure with mongoc_cursor_error().

          When      migrating      from     the     deprecated     mongoc_cursor_new_from_command_reply()     to
          mongoc_cursor_new_from_command_reply_with_opts(), note that options previously  passed  to  the  reply
          argument (e.g. "batchSize") must instead be provided in the opts argument.
