> We can optimize PatternReplaceFilter:
> * don't need to create Strings since CharTermAttribute implements CharSequence, just
match directly against it.
> * reuse the matcher, since CharTermAttribute is reused, too.
> * don't create Strings/waste time in replaceAll/replaceFirst if the term doesn't match
the regex at all... check with find() first.
> There is more that could be done to make it faster for terms that do match, but this
is simple and a start.
