Updated SAS Data Download Program in GitHub

[jimhazen]

We recently discovered a minor issue with the SAS download program made available in GitHub. There were occasionally problems downloading tables where errors were generated in the json response file but ignored because the download call itself was successful. The fix made was to include better handling of errors in the download process even when the http call returns a success. 

Customers that rely on the SAS version of the download program to retrieve data from the UDM or for CDM should update their program.
