## Updated FileLinker to Handle File Size and Md5sum

The backup workflow will only operate on files that have md5sum and size values available.

These values have already been calculated for FastQi. Adding handling for these values to the FileLinker means that they can be transferred to SeqWare when the linking process occurs.

Made the following changes:
* Updated csv parsing to allow any kind of field separator, not just tab.
* Performed a check to ensure each record supplies all required fields prior to linking.
* Made size and md5sum optional fields. If supplied their values will be added to the file entry when written to the SeqWare database.
