Uploadscript excel re-write

Ran the script to upload all the data to check if it works. The only downside to this script is JSON really messes up stuff and create mojibake (weird text mess ups) that will need to be fixed in the front end. Not the greatest solution but I couldn't find a way to make the json able to be parsed correctly. 

All ~ 40k users are able to be uploaded with all of their papers linked to them. The only errors that occur and aren't added are abstracts that aren't actually abstracts (like round table discussion).

The upload of everything takes about 1.5 hours.


One potential addition would be instead of using a continue on the first row, use it to set the indexes of all of the attributes we use. I decided against that because it would ugly up the code with no benefit, if sage uses the script on a different style of data they will need to write a new script anyway.
