* Add support for writing PCLm files. Most of the work was done by
Sahil Arora <sahilarora.535@gmail.com> as part of a Google Summer
of Code project in 2017. PCLm support is useful only for clients
that specifically know how to create PCLm files. Support in qpdf
is just for ensuring that objects are written in the correct order
and for including some additional material in the output that is
required by the PCLm standard.

* Remove --precheck-streams. This is enabled by default now
