Remove loading of hyperref

There are two issues here.  First, LaTeX wisdom (and docs) say to load
hyperref as close to last as possible, or you're going to break
things.

Second, loading it here precludes loading it later with different,
conflicting options.  Generally, ots.sty should load things that are
essential.  Put the optional things in subsidiary style files or
individual docs.
