Title: Upgrade args4j and add forbids argument to loci args 

This was added in args4j 2.0.28 and will prevent users from specifying both loci and a loci-file.

It will give the following error
```
Exception in thread "main" java.lang.IllegalArgumentException: Specify at most one of the 'loci' and 'loci-from-file' arguments
```
