Extend --count option to show the module name

[tgreenx]

From #424 (comment), it is suggested that the --count option could also list the module name of which a message tag originated.

What is the --count option? It is not available in the CLI --help text.

Hi, the --help, -h option does not list all available options, only a handful (see the option description).
For a full list, run man zonemaster-cli (or perldoc -oman {ZONEMASTER_CLI_PATH}/script/zonemaster-cli on a development environment):

--[no-]count
           Print a summary, at the end of a run, of the numbers of messages for each severity level that were logged during the run, as well as a count of each message tag. (default: disabled)
