The radar service is used by the IDV and Siphon to query for radar data. This currently has code that [only works on a local file system](https://github.com/Unidata/tds/blob/f314b60edf45bf869e9f4e066e81bcb7152552a2/tds/src/main/java/thredds/server/radarServer2/RadarDataInventory.java#L254-L289). We would like this to work for S3 files as well.
