Implement /UserUnit scaling to support oversized PDFs
...
The original PDF specification supported a maximum of 200x200" pages or
14400 PDF units. In PDF 1.6 rather than remove this limitation, Adobe
added the /UserUnit field for pages, which allows one to specify the
scaling that should be applied for user-facing numbers, while keeping
the internal limit of 14400 units.
Many real-world designs are larger than 200" in one direction. One
example is tractor feed or rolled paper which may be easier to scan in
one continuous run rather than segment into pages.
/UserUnit is independent of the pixel size and resolution of the image.
/UserUnit can also indicate very small page sizes but this is not
implemented here.

Changes to pdf page size handling
...
Changes to `valid_size()`
* accept common page sizes, such as letter and a4.
* parse dimensions of format: AuxBv#, where A is width, u is units, B is height, v is units, # are options.
* accept units: in, cm, mm, pt
Changes to `convert()`:
* resize pages based on dpi calculations
* default resize images into page size (like default resize in imagemagick)
* implement exact resizing (ignore dpi; equiv to ! in imagemagick)
Created `get_ndpi()`:
* provides dpi for page resizing
* implement fill resizing (equiv to ^ in imagemagick)
Other changes:
* default dpi in global variable

Enable support for CMYK images
...
CMYK TIFFs and JPEGs both work. CMYK JPEG2000 images have not been
tested. Adobe Photoshop and some other software generate inverted CMYK
JPEGs. The image is assumed to be inverted if the "Adobe" (APP14) tag is
present. Images can be forced inverted with `-C "CMYK;I"`, and forced
not inverted with `-C CMYK`.
