Using
empty()to detect whether a CLI argument is optional disallows falsy default values. E.g. optional flags that default to false, as with this plugin's core--resumeand--disable_intermediate_imagesflags.This PR replaces
empty()withisset(), aligning with the behavior inHMCI\Iterator\Base::parse_args().As a bonus, convert both
'bool'and'boolean'argument types to'flag'.
