v3dv: start using output control hooks

* for config file, document headers, & command line
* v3dv: sysenv, ProcessingSettings, start to use hooks to make it possible
  to control (via: the command line; the document markup header, or; the
  configuration file) the likes of: ocn, toc, segsubtoc, minitoc,
  links-to-manifest, search-form, html-navigation, html-navigation-bar,
  html-right-pane, html-top-band; these are switched on by default and may
  be switched off in omit lists within configuration file, the document
  markup header, or command line. The command line takes precedence & may
  switch on or off overriding settings within the document markup header or
  the sisu configuration file.
  * --inc- on by default, but if switched off in doc header or
    configuration, the command line --inc- has precedence; for each possible
    exclude configuration the --inc- switch that overrides configuration
    settings
  * --exc- == --no-; exclude/switch off feature (but --inc- include has
    precedence)
  * document header @build: :omit: [list output features to be omitted]
  * configuration (sisurc.yml) omit:
  exclude output feature, overrides configuration settings (omit --dev
  development branch modifier once merged back to main)
