Title: New Streams

* Multiple filters per stream
* It's now possible to append data to compressed streams
* Stream compression is reentrant (multiple calls to `compress!` will have
stream deflated only once).
* A few additional filters from PDF spec
* ASCIIHex
* ASCII85
* DCT filter is a stub as it's used only in JPEG images. It doesn't
decode/encode JPEG images.
