check for file, and get from json

JSON files being read in now for the data.
Had to do some string chopping to get the format of the  date right.
There is no specified times in the json so I left it at 00:00;
Need to generate the timecam/timestream nodes next from the other JSON.
Some more JSON would be nice.
I’m still not sure what kind of data the xml needs in terms of the
webfoot because they don’t seem to have similar enough directory
structures.
Ill get more stuff working over the next couple of days
