Match foo2zjs ZjStream output for HP LaserJet models in rastertozjs

An HP LaserJet Pro P1102 accepted jobs from rastertozjs and printed
nothing. For the HP models (-z1, -z2, -z3), foo2zjs differs from
rastertozjs in two ways. Neither changes the printed image:

• foo2zjs runs with -P, which leaves out the START_PLANE/END_PLANE
  chunks around the page data. These chunks only label the data as the
  black plane. The P1102 expects the page data without them.
• foo2zjs forces JBIG MX = 0. JBIG is lossless, and MX only limits the
  encoder's adaptive template search. The compressed bytes change, the
  decoded page does not. The foo2zjs ChangeLog (2011-11-12) records a
  firmware bug in the P1102 and CP1025 that needs MX = 0.

The Minolta 2300DL model keeps plane 4 and MX = 16.

Checked by decoding both streams with foo2zjs's zjsdecode for the same
A4 page: the chunk and item layout now matches foo2zjs -z2 -P -L0. Not
yet confirmed on a printer.

Print to HP LaserJet Pro P1102/P1102w through rastertozjs

The P1102 PPDs were unchanged Foomatic PPDs whose cupsFilter is
foomatic-rip. macOS has no foomatic-rip, so adding the printer in
System Settings failed with "The software for the printer was installed
incorrectly". The PPDs now hand CUPS raster to rastertozjs.

rastertozjs reads the model from the PPD's *cupsModelNumber (2 = HP Pro),
because CUPS does not put PPD defaults into the job options. A "Model"
job option still overrides it. The model selects the P1102 variant of
the job and page headers; it does not change the image.

The PPDs also set 1200x600 dpi, the only resolution foomatic-db allows
for these printers; it excludes 600x600. This sets the printed image:
cgpdftoraster renders 1200 pixels per inch horizontally, and rastertozjs
sends them as two pixels per 600 dpi dot (VIDEO_BPP 2). Without a
HWResolution setting, cgpdftoraster renders at 100 dpi.

The other ZjStream PPDs still call foomatic-rip and all claim
*cupsModelNumber 2. Each needs its own model number (from the -z flag in
its FoomaticRIPCommandLine) before it is switched to rastertozjs.
