Add support for ArrayCache to FilterOptions and its subclasses.

Note that nothing actually uses caching yet.

Subclasses must now support ArrayCache:
  - getOutputStream(out) -> getOutputStream(out, arrayCache)
  - getInputStream(in) -> getInputStream(in, arrayCache)

FilterOptions now provides the old getOutputStream(out) and
getInputStream(in) as wrappers that use the default array cache.
