* docs: fix some Codacity recommendations

* chore: update copyright year

* style: more codacity fixes

* style: fix issues reported by Codacity

* style: fix and add spelling check

* Update .pre-commit-config.yaml

* Add configuration output multi-line description tests

This adds tests for the application's description as well as option
groups and subcommands.

See #592.

* Fix commenting of configuration output multi-line descriptions

* Fix excessive call to subcommand's final_callback

When parse_complete_callback_ is set there is an extra call to
run_callback() inside the App::_parse(std::vector<std::string>&) method.
This extra call also excessively calls a final_callback_ (when it is
also set) for the command and (since it is recursive) for it's
subcommands.

This commit adds extra boolean parameter for the run_callback() method
allowing to explicitly suppress calling to final_callback_. The value of
this parameter is also propagated to recursive calls to run_callback().

Fixes #572

* fix: main app should run final_callback, add tests
