Increase field size limit

[kevinschaper]

The uniprot map from the GO Annotation load has a row that's 900,000 characters long, which has a field that goes way past the default 130k size limit.

We can bump the limit up with: csv.field_size_limit(sys.maxsize)

It turned out that the super long rows weren't actually rows that we need, so I'm going to close this until we come along another 900k row. (unlikely...I hope)
