This commit replaces the previous command-line argument parsing with
program-options-lite, which additionally serves as a simple config-file
parser.

A table based configuration of options provides in a single place
option naming, help text, and default values.

Side effects of this change are to:

 - adds further error checking for unknown arguments (warning only), parse
   failures, required options.

 - replace the default constructor of Parameters,
   PCCAttributeEncodeParamaters, and PCCAttributeEncodeParamaters
   with defaults in args handler

 - updates the type of Parameters::mode & ...::colorTransform to be more
   more descriptive.

This commit allows option target storage to be of the form V<T>, where
V is a container supporting .push_back().  The default parser tokenises
the argument string using commas or white space characters, with adjacent
white space characters being merged, and commas are not:

  "a, b,c,,e" = {T1(a), T1(b), T1(c), T1(), T1(e)}
  "a  b c  e" = {T1(a), T1(b), T1(c), T1(e)}.

This enables use of lambda expressions and bound functions as
argument option helpers -- helpful when having to perform some
complex action on variables.

The Options collection already knows the default value for each
option.  This commit extends the help text to show the default
value against the long option name.

The following cosmetic changes are made:

 - tidy output of error/warning reporting without location context

 - help: fix minimum spacing between options and help text

 - help: add blank line before options whose text collide with help text
   to improve general readability

 - help: widen the options column to reduce number of overlaps

In order to facilitate config file handling, this commit imports the
program-options-lite module from jctvc-hm.  Subsequent versions will
update needed functionality.
