Discrepancy between the wget commands and the srst2 command line.

[Redmar-van-den-Berg]

Fixed a discrepancy between the wget commands and the srst2 command line in the readme.

I also get a different output from the example, but I did not want to include that in the readme because I'm not sure how relevant the difference is.

$ cat serotypes__genes__EcOH__results.txt
