Seg fault when number of channels doesn't match number of items in data records #10
Description
[props to Dömötör for reporting this]
When the datastore receives more data in JSON than the number of channel names, bad stuff happens.
Example below is from data upload via ESDR, but the underlying issue is with datastore import.
For example, this:
PUT /api/v1/feeds/[FEED_API_KEY] HTTP/1.1
Host: esdr.cmucreatelab.org
User-Agent: HoneyBee/7.18 (Dylos/1.1)
Content-Type: application/json
Content-Length: 1116
