implement ASCIIHexDecode filter
About
# PDF as a file system
Yeah. WIP.
There is nothing to look at yet. You can build it and run things like
`./6.out my.pdf Root Pages Kids 0 Kids 0 Kids 0 Contents .` to dump a
specific object (text, images, fonts, etc).
## Installation
mk deps # install additional decoders (jbig2, jpeg2000)
mk install
## TODO
* CryptDecode filter
* does DCTDecode filter need to deal with ColorTransform?
* do we need predictor 5 ("optimum")?
* object stream dictionary doesn't support `Extends`
* jp2: CMYK color space support needs to be added
